My "08" Arctic Cat 650 H1 runs (plows or runs a trail) great for the first 15 minutes. I can get all the power needed. It starts cutting out when it gets warm/hot. There is no heat error and plenty of antifreeze, new spark plug and air filter. Not sure where to go from here. New coil? Have the valves checked? I would take it to the shop, but the waiting list is 3 weeks and I need it to plow snow.
Any ideas???
Thanks
