Could be possibly the ignition amplifier mounted by the drivers side headlight. Mine died a few times than would restart and then died for good.. Have you checked for spark?

Mine just went thru a shutdown back on March 2 and like you I posted and got some good advice. Here's what I did in order to eventually determine my pump was locked up.
1. Verify 25 amp fuse is good
2. Verify 8 amp fuse for main fuel pump is good. (probably ok but easy check)
3. Either resolder the fuel pump relay per instructions found in abundance here or borrow one to test your vehicle.
4. Open oil fill cap and have someone crank while you make sure the cam is turning to rule out broken timing belt.
5. Disconnect the fuel line to the common fuel rail and have someone crank the engine while you hold the fuel line in a bucket - you are testing whether you are actually getting fuel from the main fuel pump with this test.
6. Remove fuse 4 and 6 and put a jumper across the left side terminals and see if you get fuel out of the hose you disconnected above.
7. Lower fuel pump carrier and disconnect the yellow and the black terminals from the main fuel pump - Run a jumper cable from the positive side of the battery and a ground attached to the driver side dome light switch to supply direct voltage to the pump to determine if it's locked up.
8. Pull the entire carrier from the undercarriage of the car and replace fuel pump (and $10 filter if you want)
9. Torque the inlet bolt to the filter from the pump to 25 ft lbs to ensure no pressure leak when you get it back together (ask me how I know this).
10 Start it up and drive away happily.

Hi there,

I agree you should clean up the 25A fuse wiring. That will shut it down just as you described. So will a cracked solder joint inside the fuel injection relay. And the crank position sensor (CPS) with the old yellow band (did you know this part made the inside front cover of the '89 quick parts reference manual?).

You've already gotten this advice. What I can't for the life of me figure out, is why one of our members would give you a "thumbs down" for posting a legitimate request for advice. Some welcome from some zany wannabe moderator, I suppose. Ignore it. Maybe it will eventually go away.

Families are like fudge...mostly sweet, with a few nuts.

I'm thinking fuel pump relay, although that normally exhibits itself at startup, or a bad crank position sensor (most likely). The crank position sensor is mounted behind the cylinder head where the engine meets the transmission. Check the harness that comes out of it, if the insulation is cracked/shot, replace the sensor.

Have you checked and cleaned the 25 amp fuse on the driver's side fender well? How about cleaning and tightening the ground wires and battery cables to the chassis etc?
