Welcome to Quadcrazy @Susan Makowski-DeGraw 

Sounds like a fuel issue to me especially if its only 10 mins in when the problem starts.   Could be wrong but I would check the fuel delivery first.  Since it could be in the tank or the carburetor my first thing would be to cut the fuel line and install an in line clear filter.  This will allow you to see two things. 
1. If the filter shows no fuel inside then you know the tank has a partial blockage.  
2. You will see if the filter is getting dirty. 
If there is a fuel filter already  in place then check/replace it. 
In addition to this you could be experiencing vapor lock.  This happens when the vent hose or hole on the top of the has cap is blocked.  It stops fuel from flowing to the carburetor. loosen up the gas cap and and see if the problem stops.  
If none of that works then it could be inside the carburetor and thats going to take a little work.  Nothing you probably couldn't handle! 
Thats all fuel related items. 
 

Electrical: Regulator/rectifier could be heating up and failing. Easy enough to get and change. Its plug and play. 
Ignition coil could be doing the same and again its easy as the regulator/rectifier to replace.   
 

Start with the basic stuff first and go from there.   It could be something silly. I always like having a fuel filter in place though so either way I would add one.

Ok so there is an injector on the bike. There are a few things to look at. 

1. Could be a bad injector that quits after it gets hot.

2. Fuel pump is quitting after that 10 min period. Have you turned the key off and back on to see of it re starts? And if so when you turn it off and turn the key back on listen for the pump coming on.  Its a low sound so listen carefully. Should be a  hissing sound for about 3 seconds or so. If you don't hear that then it may be a pump or relay issue that's getting hot. Every time i turn my rancher off and the key back on i hear that pump come on for a few seconds before i hit the start button. 

3. Your TPS (throttle positioning sensor) could be bad or out of calibration. They sell a calibration tool for that.  

4. Im a little stuck on the regulator/rectifier getting hot and causing this.  
 

Make a list of the above and tackle one at a time. Im sure i missed a few things to look at and someone will chime in but at least you have a starting point for now.

I have replaced 2 fuel pumps on Rincons that had very similar symptoms as you have. If you have access to a fuel pressure gauge then that's where I would start. If I remember correctly, there is an internal fuel filter that is mounted in the fuel pump housing located just above the pump that is not replaceable or shown in the parts diagram along with the one that is on the bottom of the pump that is replaceable. These are worth checking out also.

Hi. You can't fit a regular clear plastic filter to a fuel injected bike.. They have about forty pounds of pressure in the lines and it could burst and start a fire.

I'd be suspecting an electronic fault. That time related aspect sounds like an electronic component getting hot then failing, then cooling and starting to work again. I'd suspect cdi or ecu.

That said, there was a case in here the other week that turned out to be a tight valve clearance. Checking the valve clearance would be a good idea.

And, in all problem diagnosis they always say as the first step.. do a standard tune and check everything is to specs.. So fuel pressure, voltage, aircleaner, tank vents ..  It's boring but you really want to know everything's right before you start fitting parts..

      Howdy ya'll. I am working ona 2000 Yamaha Breeze 125. It was in rought shape when I received it and I am working through issues as they pop up. The quad had been sitting for years. I was able to get her running again, but I need your help with the following issue:
      I don't trust the transmission yet and I don't want to make problems any worse. So, I haven't pushed things hard at all. Low rpms, less than 5mph in reverse.

      Nuetral: Runs as expected
      Reverse: She seems to be driving fine at slow speeds. Going into reverse at idle is fine, coming out of reverse back into neutral won't work (the shifter is just stuck). As soon as I turn off the quad, I am able to shift around without any issue.
      Forward: It slips. It seems to only transfer power to the wheels on a smooth surface and going slightly downhill. When shifting into forward at idle, there is a clacking sounds during the transition. Shifting back to nuetral works just fine.

      Other Notable Symptoms: There was old oil in the vbelt and when I was tuning the carb, it starting blowing out of the CVT cooling vent at the front of the quad. Made quite a mess. There is positive crankcase pressure due to piston blowby, that I have not decided whether or not I am going to fix (customer budget dependant).  Since the oil was old, much darker than the new oil that is in the crankcase, I am thinking it seeped past a bad seal while it was sitting for years. The oil that was in it when I first got it had gas in it.

      Thoughts: I am thinking maybe there is an issue with the clutch. I worry about the old oil intermingling with the dry centrifugal clutch. I was thinking my next step would be to take the cover off of the clutch and inspect it.

      Let me know what you all think. Any advice and ideas is greatly appreciated. This is only the 3rd quad I have worked on and I have a lot to learn.

      Hi guys, I have a 2004 big bear 400. Last winter while plowing the driveway, I heard a loud pop from the left side of the engine. It continued to run as I looked for leaky fluid, but then died shortly after backing it up and won’t start now. The oil light comes on when I try to start it, no noise or anything else. 
      No blown fuses that I can find.
