Hi Jim,

I doubt very much you have any failed fuel pump. This sounds to me like a failure to get the electricity to the pump, not a failure in the pump.

The pumps will outlive anything else on the car unless continually starved of fuel by a non-operating tank pump or rotted hose in the tank. Even then, the dying pump makes so much noise you'd have to be a teenager with a 1000 watt stereo not to notice its cries for help. In short, look for simpler troubles getting the voltage to the pump, which, in the case of the LH2.0 you drive (assuming non-turbo), is mostly in the battery wire and 25A fuse. The pump is solid. The relay is solid, in LH2.0. Measure the voltage at that connector under the seat when it is running poorly. Check your work with the wiring from the last pump replacement.
