Is it a fuel problem? Connect a fuel pressure gauge to the fuel test port and monitor it while driving. If the pressure stays it probably isn't a fuel problem.

Diagnosis...attach a test wire to the fuel pump with a test light bulb in sight while driving. If the light goes out, power is being lost to the fuel pump. Probably due to a bad fuel pump relay. If the light stays lit but the pressure drops it's the pump. If the pressure drops and the light goes out it's probably the fuel pump relay.

My guess without diagnosing is a bad fuel pump relay, they are inexpensive and easy to try; however, remember stalling can be a real safety hazard.

Has the wire harness been replaced?

Good luck!!!
