I can't say how the pump reacts on a 5.3 but when the pump dies on a 62 it's just dead no slow make it home.

I have heard of similar symptoms turning out to be the the alternator dying. I had some flickering dash lights shortly before the alternator died in my diesel. The best part of the diesel is that I drove around all day with a dead alternator, motor didn't care.

On newer OBD2 engines a flashing check engine light means a missfire that could damage the converters. Pull codes and see whats going on. Insufficient fuel due to a failing pump could cause this. There will be lean codes and missfire codes if it is a fuel supply problem.
