WHY VEHICLE WILL START,BUT QUIT RUNNING AFTER A COUPLE SECONDS

1999 Chevrolet Blazer • 150,000 miles

It starts right up but after a couple seconds it quits, has had a fuel pump and filter replaced within the last year. I replaced the mass air flow sensor, but no luck, it has done this before and if I removed the wire to mass air flow sensor a few times then it would start, now no luck with doing that

Clean the idle air control valve and test the TPS and MAP sensor-start here and then let us know-
