I had my boat out yesterday and my kicker motor wouldn't fire up so I had to do some trolling with my main motor. After trolling with it the day before for at least an hour just fine and yesterday for 30-45 minutes it all of a sudden sputtered a little and died. It fired right back up so I put it back in gear and it went another minute or so before dying again. I opened it up to WOT and it jumped right up on plane and ran fine and then we tried trolling a little more and got 5 minutes or so of trolling in before it died again and we called it a day. Any thoughts or suggestions would be much appreciated. Thank you
