My 90 5.7l has the same issue (among a plethora of others) if I remember correctly the issue with that generation for that particular fault (at least in my case) is with the oil pressure switch which is inconveniently located behind and below the distributor. My particular instance isn't as much the switch itself but in the wiring, there is a short in the wires that causes the switch to read no pressure, the computers in that generation are designed to shut the engine off at too low or no pressure. I'd replace the switch and check the wires for it as far back as you can to make sure there's no short in them as well.
