Yesterday during our ride my buddies RMK would not want to start after sitting for a few minutes.The first time after trying to crank it with the elect start it was a no go.We switched plugs and it made no diff.I was then able to restart it by pull start a few times.Sled ran great other wise.This issue happened 3 times during our ride.Sled only has 750 miles on it all stock.I am thinking TPS sensor any thoughts?
