Thanks YC 1... interesting reading. The tech was voltage testing the two sides on mine while I watched and when it clicked he said it was trying to transfer to the house side but wasn't doing it because there was no charge going to that side.
What do you think about that being able to put a heavy enough load on the chassis side to pull the voltage to the ECM down enough momentarily to cause an engine shut down? Obviously that is not a common occurrence or there would be lots being said about it.
I think that my problem has been the ECM is getting some kind of electrical signal or drop in voltage that is causing it to shut down and the question is where and what is doing it. And... why would disconnecting the batteries reset anything and cause it to stop happening?
At this point the relay being bad is clear and needs to be replaced but whether it could be a factor with the more serious problem is just a guess.
Also... one other thing that was done while I was there and the computer was hooked up was he down loaded a updated software program.
