Bad/weak spark plugs can also cause some funky issues.
Spark plugs are brand new, fewer than 5 hours.
Lol I been down this road before I got a four wheeler that will start and run like no tomorrow and then it won't start you'll check fuel you'll check here you'll check everything guess what you put a new plug in it and runs like a top until it does it again even went to my four wheeler and my outboard repair guys and they said yep too they say after a couple hours of pulling on a big old sled that you learn faster to just change the plug... the third time of 6 months that it happened to me I even have the NGK plug sitting on my desk at work to ship back to them and ask them why .......and no it ain't nothing else on my wheeler that's broke you can give it ethanol you can check everything change the plug boom it'll start .....put the other plug back in won't start put the new plug back in boom it'll start unbelievable but....
