Honda rancher 420 shuts off while riding fan not coming on.

When running for a while the rancher will shut off without the fan turning on. We then took it to dealer where it was started and warmed up. The fan came on at the dealer so they then replaced the fuel filter and fuel pump. We got it back and ran good for a few days with the fan coming on when needed. Now its back to shutting off before the fan ever comes on. It seems like the time the fan should come on the bike shuts off. It will start after letting it sit for a few minutes. Any ideas of the problem?

My guess is a wonky  temperature sensor.  Like all electronics /  electric relays and switches , they  can go  intermittent----  work  one time and not the next, then  work  and fail again at random times. I'd replace it and see.  I'm  not  a  Honda dealer or service mechanic but I can't see their thinking in replacing the fuel  pump and filter when the  bike  runs fine until warmed up to the point the fan  should come on.  That's not a fuel starvation issue  that should show up well before the motor reaches  operating temperature.  That  points far more to a sensor/  fan circuit problem to me.

      I generally use Non Ethynol fuel in all my small engines. I just got back from the gas station and that fuel has really increased in price since last year, I will continue to use it, even though its north of 1.00 a gallon more. That seems minor compared to cleaning and repairing carbs every year. 
      I was just curious as to what others are doing in regard to gas in their quads, i know a lot of the newer ones are fuel injected which shouldnt pose a problem, but i have had lots of problems with rust and jell forming in carbs when using ethynol fuel.

      Hi, I am having issues with my TRX350D fuel pump.  It suddenly stopped running so I have replaced all the fuses and cleaned all the terminals.  I have fitted a new pump, fuel cut-off relay and rectifier.  Still nothing!!  The pump runs when attached to a battery.  The engine will start on the choke and the filter fills with fuel but it will  not rev and dies when the choke is closed. I have power to the relay but nothing at the pump black/white wire when cranking the engine.  Any ideas where to go from here would be very much appreciated!!

      Hi all,
      Looking for some help on a starter/bendix issue. Can Am outlander 450 2017. While cranking to start, the starter spins and engages into the ring gear. After a few seconds the bendix retracts while still spinning and there is no damaged teeth on the drive pulley.

      Have a 1998 AC 300 2x4, Just installed a new carburetor. Engine starts easy but the choke RPMs are very hi and take along time (5-10 mins when cold out). After engine has warmed up choke releases and it idles and runs fine., It does no have an electric choke. The choke lever is never used and it seems like an auto choke? Long story short, how can I lower the choke rpm levels?
       
      Also, carb came with a spare145 jet, not 100% sure what is installed. Could this impact choke RPMs?
       
       
      Any help and information greatly appreciated.
