I have this engine in a 19.5 Lund. Starts great when leaving home. Run 15 min. on plane. Stop to fish. Try to start after 1/2 hour or so and engine will not start, just backfires once or twice. Gas is new. Have changed water separating filter. Have tried with gas cap removed. Have run with no cover on engine to keep cooler. Got towed in by 12' alum. today. Please help!!
