If the fuel pump relay is losing contact the oil pressure switch should keep the car running. There is a plug in connection in the top of the tank, inside the tank, and I've seen this get corroded, even burnt, and cause just what you're seeing. I'd hot wire the pump for a few days to rule out all other stuff before dropping that tank again though.

Hotwire as in run a wire direct from the battery to a toggle switch to the pump. That will rule out the ECM and sensors.
