My boat will stall intermittantly and will be hard to start afterwards. Its pretty odd and usually happens in shallow water when idling. It will stall and then not start for 10 min or so. Usually if i let it sit then it will fire right up. I can shut it down 2 or 3 hours later and then fire it right back up with no problem. It just happens every once in a while but it is pretty fricken awful when it happens while I am waiting to load up and then I am powerless at the docks with 10 other boats circling around while waiting. I almost beached it on rocks this weekend when it happened. Any Ideas?
