Replaced the fuel pump and it starts but does not continue to run. It dies out as if losing gas pressure after idling smoothly for a short time

Change fuel filter and check that the fuel pressure is as per specs pressure should be 40-47 psi with modulator vacuum hose disconnected and 30-38 with the modulator vacuum hose connected, if there is on change in the pressure the vacuum pressure modulator is probably faulty.
