When the car stalls the light will remain lit, and turn off about 2 seconds later. So I guess the pump is getting a good 12v source. Seeing as how the pump dies before the light, I can assume that the fuel pump itself is bad. Correct?
If the fuel pressure is dropping BEFORE the light goes out, then I'd guess the pump is failing.
I had a boat once, that would run for a minute or two and the engine was die. Mouse in the fuel tank kept getting sucked into the pickup. Fuel pressure would drop, engine stall, then the mouse would float away from the pickup and I'd be able to restart the engine. Food for thought.
Anyhow. if the fuel pressure IS in fact dropping it's pump related. Rule out ECM, FP relay, etc since you have good power. If the fuel pressure is NOT dropping, i'd move my bet to ignition.
