John, I have DD 8.2L engines in my 42, but there is very little in common with the 671s. However, I suspect your engines have Start/Stop solenoids. Maybe Kerry can confirm this or otherwise. If you have them, it is possible the one on the problem engine is malfunctioning -- such that it only opens the fuel to the engine rarely. I'm just guessing here. But it is an idea you can research.
