Gets hot, runs horrible and then stalls and won't crank
 

I have a 1995 Yamaha Warrior 350. My problem is when it gets hot (5-10 min of riding) it runs like crap (starts to break up) and then it will stall and won't crank til it cools down. http://images.ibsrv.net/ibsrv/res/sr...es/biggrin.gif Any info would be much appreciated.http://images.ibsrv.net/ibsrv/res/sr...milies/nod.gif
We have put a new air filter, oil filter, oil, and cleaned the carb on it.http://images.ibsrv.net/ibsrv/res/sr...milies/huh.gif

Check the gas tank vent. The tank might not be venting correctly and causing too much vacuum in the tank to pull fuel into the carb after running for a bit. Try driving around with the fuel cap removed see if it still stalls.
