Just a hunch, had this happen to a bike of mine years ago, could be the piston rings are gettting ready to go(wore down). What happens is when the quad is cold the rings expand tight into the cylinder walls allowing it to get full compression and run ok. When it heats up they shrink allowing the slightest amount of give which in turn will cause you problems similar to what your describing.

Carburator clean up could help solve the problem, it seems some dirt may have entered the float chamber!
Blow the jets with compressed air.
Hope this helps!

i had the same issue. it's gonna be a blockage in one of the vent tubes to the carb. check the line to the left of the carb that runs next to the gas tank. if thats fine then check the gas cap line. then if thats all good then check the line that runs below the carb. these are all vent tubes and allow the carb. to refill with fuel

It sounds more like a fuel problem to me. If I had to guess, I'd say that for some reason your bike has started to run lean. The lean mixture is causing your engine to run hot. The heat from the is "perculating" the fuel in your float bowl and causing it not to start. I've seen it before on race cars.
The mixture on your bike may be running lean for any fo several reasons. You could have trash in one of the jets in the carb or you could have a vacuum leak. I'd put my money on the later. There is a hose that comes off the backside and feeds vacuum to the VOES switch. Make sure this hose is intact and doesn't have any cracks in it. I'd also replace the intake gaskets at the heads and the carb seal provided the carb is the original CV carb.
If the carb has been changed to something else, there could be other problems as well. Also, make sure your not running gasoline that has a greater than 10% ethanol mixture in it. The greater the percentage of ethanol (alcohol) the leaner the engine will run.
