So this morning. Brought the boat to the lake and it fired right up and ran perfectly. Get to my spot and fish for a bit. Went to make a move and it wont start. When cranking I can smell gas. Primer bulb is new. Can hear the fuel pump running and injectors snapping. Checked spark plugs which are new also and they looked good. Had this happen to me once before but with in minutes it started. This time I had to be towed in. What is going on.
