A problem cropped up this weekend: When cruising on plane my port engine started cutting out. I first noticed it stumbling occasionally, then it started dying completely. When I stopped, sometimes I could turn the key off, then back on and it will start immediately. Other times the ECM and fuel pump would cycle up, eng will turn over but not start. A few minutes later it usually would start again. I started with the easy fix- changed the water/fuel filter- no help of course. The next day I turned the key- nothing powered up. I left the key on and started jiggling and pushing on the electrical connectors- when I touched the coil wires- the eng cycled up and then would start. The connectors still have lube in them and look in no way rusted or corroded. I managed to get the boat home with it stumbling occasionally and dying a couple of times but obviously it wasn't just a loose connection. I felt the coil when I got home and it wasn't hot like they are supposed to get when they fail. Anybody out there have any suggestions??
