IROCKET76

Ok getting very tierd of a problem Ive been having with my boat. I have a 232 Baja Islander with a 454 mag fuel injected 1998. Went out yesterday with an almost full tank of fuel ran great all day ran it very hard most of the day no problems. At the end of the day made one last hard pass then went back to idle. When I went back to throttle up to put it on plane it cut out and almost died. Came back down was missing the then started to idle just fine. Idled fine and reved up just fine but would not go back to plane fuel at half tank now. whats up with this 75 degrees out water was at 65 motor temp was 178 or so running no ethenol and have good fuel pressure. whats next
