I have two 99 sportsmans and when we went riding the other day one stopped running after about 3 hours of riding. It would start for about 30 seconds and then shut off and let it sit for a while and it would do the same thing. I know it could be floats sticking, machine overheating, stator shorting, ..... Just wondering if anyone else had this problem and what fixed it. Since then it has ran fine in 30 minute runs but am afraid to take it on another long ride.
Thank You

Try checking the fuel vent line I had mine melt against my pipe and thats how it acted.
