2007 Honda Rincon 680 Runs, ride 10 minutes, then dies

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..
