Idling around the marina, the engine doesn't seem to have a problem (it is on a 4-person RIB). Head out onto Lake Michigan, get the dinghy up on plane at about 80-90% throttle, run it for about two minutes or so, and the engine just dies. No sputtering or anything. It is as if the fuel is simply cut off. Sit for a bit and I can then start it again using the choke, but is very tempramental as I limp back in. I tend to have to alternate between choking and not. Often dies multiple times while limping in.
Thoughts? It has new spark plugs gapped properly and I've checked the fuel filter.
