Cheek the spark plug cap mine did the same where the spark plug is can fill up with mud whn you wash it Thea's a small hole on the right hand side of the head just next to where the radiator hose goes in it's a drain hole but can get bloked whn washing and whn the motor gets hot some how pops the cap off pull the spark plug cap off and give it a good clean around the spark plug make sure all the dirts and and make sure it drains out the hole thn glue some foam under the tank so it sits hard down on the spark plug cap

Well being a 16 it shouldn't be the TPS. It sounds a lot like our 15 problems, which turned out to be the TPS. I agree with above check the spark plug cap. Good luck, please post your findings!

I think you need to check when it quits and see if you have spark at the plug, if no spark disconnect the kill button. If you have spark check the fuel pump to see if your getting gas.
