Over the last few weeks my engine would misfire on occasion when at wide open throttle. Some times just a little blip, other times I would have to go to 3/4 throttle to get it to stop misfiring. Just last night I ran 3 miles across lake wissota with no trouble at all. I stopped and fished for about 45 min then started the engine again and was going to head up just a little farther. As soon as the boat got on plane the engine killed as if I had turned the key off, no spit or sputter at all. I checked for spark when I was on the water and there was none. Tonight when I got home from work I thought I would put the muffs on it and try to start it. Soon as I turned the key it fired and ran perfect. I let it run for about 5 minutes and then shut it off and wrote this message. Where do I begin with this thing, or what do you think the culprit might be? Just a note I worked on helicopters for 5 years so don?t be afraid to put me to work with troubleshooting this thing. Any help would be greatly appreciated.

I've seen that on a couple of those 150 Loopers. The problem on both ended up being the powerpack.
