My 97 tahoe with the 5.7 vortec was running fine then randomly died and wouldn't restart. Wasnt able to mess with it for a few days and when I was able to get to it it of course fired up and ran fine. That was several weeks ago now and has continued to run normally. I've watched fuel trims checked wiring and everything looks good. I'm leaning towards a fuel pump that's working when it wants. I've had vehicles before that didn't out right die the pump would come and go. Is there a way to test for that? Right now I get 60 psi with key on. I just don't want to drop the tank if it isn't a pump issue
