Default 04 trail boss stall

Does anybody know if the trail boss thermistor will shut the machine down when it gets hot? It seems to happen when I ride for about an hour or so.

sounds like its vapor locking. make sure all the vent lines are clear and not pinched. as well as the gas tank. if you unscrew the gas cap does pressure exscape? there shouldnt be any pressure. just a thoguht.

I did notice that when it stalls if I lift the pull starter handle there is vapor build up in the crank case. I tried the gas cap and checked the vent lines. They all looked good. What now?

does that have check valves in the vent lines from the carb? make sure thier working right. should only pass air one way. when you say hot, you dont mean over heating do ya?

It's not over heating. I'm not sure about the check valves. I'll look tonight. Thanks for your input.
