I have twin 2006 150s where the port engine cuts out (immediately cuts out, does not sputter) randomly when accelerating or if left idling at the dock for about 20 minutes. No alarm codes go off and the engine is not overheating. Once it stalls it will not restart for about 3 minutes. You can turn the key and get the green oil pressure light but no BEEP (yes the engine was put back in neutral). The engine will attempt to start but will not turn over. Once you wait about 3 minutes OR turn off the starboard engine the port engine will then BEEP when you turn the key to the first position. I'm not finding any leaks in the fuel and the fuel filters have recently been replaced. I disabled the kill switch on that engine just to make sure it was not a faulty kill switch. Also, this is pretty random and usually happens at the beginning of the trip. Once you restart once or twice the engine will then run for hours no problem. Any help would be much appreciated!
