Default 93 Bonneville SSE sometimes stalls - no rhyme - no reason

93 Bonneville SSE - V6 - 130k - My dealer has had it more often than I have.

Drives just fine then car stalls for no reason.
Always turns over, plenty of power from battery.
Just dies, no warning usually at low speeds.
Will not restart.
Wait 30 or 45 minutes, car starts and runs fine.

Car won't re-start.
Run errands.
Quick in and out of store.
Come out of store, get in car, car turns over but will not start.
Wait 30 or 45 minutes, car starts and runs fine.

Car does not stall at high speeds.
60 or 70 mph on the highway, car is a beast.

Dealer has looked at it 6 or more times.
Says that they don't read back any codes that tell them anything.
Fuel relay was replaced about 6 months ago.
Dealer says plugs and wires and everything checks out OK.
They say they can't figure it out, and I can't fix it myself, so I am screwed.
I'm driving a ticking time bomb.
Fortunately, it has yet to stall in traffic or someplace dangerous.
Now, I am afraid to drive it and I'm thinking about scrapping it.
I need a car asap.

Should I give another dealer a crack at it?
I can leave it with a local dealer for five days starting next week.
Anyone have any ideas?

Mine is a 90, although I just fought the same symptoms with it. With the help of this forum, I found it was the crank postion sensor.

Unrelated, but we had a similiar problem a few years ago on my sisters 91 Grand Am. Turned out to be the ECM fuse loose in the fuseblock, tighted up the prongs a little, put some De-Ox on the fuse, and that car is still beating around daily today.

I hope they get it fixed without throwing lots of part$$$ at the problem

Fuel & Spark, Fuel & Spark. You need to check a few things when this happens again.

Carry a spare plug so you can check for spark at the three front cylinders.

You'll need a fuel pressure gauge so can check for fuel at the rail.

You can check to see if the fuel injectors are being pulsed with a #194 light bulb. Straighten the wires on the bulb, remove the wire from one of the injectors & insert the bulb. The bulb should pulse while engine is being turned over.

If you’re usually by yourself when this happens you'll also need a switch so you can turn over the engine while you’re under the hood. All this should cost less than another trip to the dealer. Try all three of these checks while everything is working so you'll how everything should work.

PS - If you'd prefer to try something instead of waiting for it to stall again then the crank sensor was an excellent suggestion.
