Your symptoms indicate the fuel pump as about third from last as the likely culprit in my book. All the usual suspects are first. Lets assume this is a Bosch LH2.4 car (round coil, automatic).

Fuel Pump Relay (actually, I think it is a "system" relay on your car)
RSR if you have it
Power stage
Fuel pump relay socket melted or oxidized

I would suspect all of these and more before jumping to the Bosch Main pump. Yes, you have 1/2 million miles and if it is the original pump, it owes you nothing. But they rarely go bad and this behavior is not common when they do.
