Could be as simple as a loose ground.
Most of the things that have been replaced could make it run badly (or not at all) if they were bad, but the random shut off that runs fine the rest of the time is not easily connected to most of them.
Were these new ECMs?
Tried 2 different brand new Ecms. I will go through and check the grounds tomorrow thanks.
