I do not think this is a fuel problem. I could always be wrong.

But...both fuel pumps are new, like brand new, and were installed between the first and second occurences of this problem.

This was done for reasons having nothing to do with the sudden death. The main pump was making a terrible noise and the tank pump sounded real wimpy. I should have done a volume test on the tank pump but I had a new spare so I installed it as well as the main.

I am more than familiar with the Lambda system. The frequency valve is happy as a clam. I listen for it's operation from time to time through a cardboard tube about 4 inches in diameter and 42 inches long. I did so recently and it is working. This is confirmed by the 50% duty cycle I saw yesterday when I checked with a dwell meter. I don't see how a problem in this area would cause the symptom I have experienced.

Before the first sudden death I had, in fact, checked my fuel pump relay and the spare I carry in the glove box. Both are good.

I just don't think this is fuel related.
