After checking I was able to isolate the cause of the failure. Fuel pump
relay# 1 would lose power at times.
Using the 8A section page 8A-22-6. That relay controls fuel pump relay #2
Replace fuel pump relay #1( 20 plus years old ) and car started right up.
No guarantee that this might be your problem, but it gives you something
to look at.
Hope this may help you.

This is a very interesting thought and would be a pretty easy check, thanks!

When you say single fuel pump, you mean modified pump running on one pump?

I used the Flyman pump assembly, you end up removing/isolating the 2nd pump wiring.
