I have a 2014 pro 800. Went out riding yesterday sled ran good all day. Went out the next morning and it wouldn't start and had no spark. Was going to take it to seeley lake a few days later befor I left I pulled it over and started right up. Rode around the yard about 20 min and shut it down. Went and eat lunch came back out and wouldn't start. Waited a few hours tried it again and started right up, and has been running good ever since. Should I trust it????
