Still dies. I finally bought a TECH 2 and we are going to hook that up with it set to capture error data and drive the **** out of it until something happens. With the TECH @ fully dedicated, we hope to get this solved.

I resolved my 94's sudden stalling/dying after testing the fuel pressure. Turned out to be a faulty fuel pump relay, located under the dash on the passenger side. The clue was the fuel pressure suddenly dropping from 43lbs to about 10lbs, causing the engine to quit. I'm still planning to replace the fuel pump/sender/sock as a unit, because the car sits a lot. The fuel filter was replaced 20k miles ago.

1992 Corvette Stall Issue

I recently replaced the fuel pump relay under the passenger side however for the diagrams that I have available to me show that is two of them. One under the drivers side and one under the passenger side. I knew the location of the passenger side one therefore I replaced that one. But what about the other? is it worth replacing?
Has this fix stayed true? Or has the car stalled since?

I believe the driver's side fuse/relay is actually located in the oil pressure sensor/switch, which is on the back of the engine. It's a dual-function sensor, which sends a signal to the ECU to cut off the fuel supply if oil pressure drops below a specified reading.
The car performed flawlessly, cold or hot...for a few days. Then, it stalled twice within 50 yards, at 30mph, but immediately restarted and drove normally. A few weeks later, I started it in my garage and, as it was warming up, it died. No codes, no SES, coolant digital temperature was 144 F, oil temperature was warm, too. It immediately restarted and I let it warm to full operating temperature without any problems. However, I didn't take it for a drive.
Bad ground(s)? Sensor(s)? ECU? I'm pretty sure it's electrical in nature, because
Back to the drawing board...
