Fuel pump may have been replaced, but whoever replaced FP used fuel immersion rated hose (SAE 30R10) between fuel pump outlet and feed through? Regular hose fuel hose softens if submersed in fuel. Get a fuel pressure gauge and verify that you have 9 to 12 PSI at all times.
A bad ignition module or flaky reluctor coil may appear as fuel starvation since ECM must have DRP pulse from dizzy to fire injectors. No DRP, no injectors firing -> looks like fuel starvation.
