1991 Bonneville Dies After Running 15 Minutes

1991 Bonneville with 3800 engine, 60,000 miles. This car starts and runs 15 minutes or so at an idle and then dies. The engine turns through well but will not start again for hours. At that point it will start and run 15 minutes and quits again. I have not put it out on the road to try it fearing a tow truck bill. Anyone know what would be the first troubleshooting steps I need to take?


Is it paranoia if they really are out to get you?

Have you had the codes read?

My first thought is crankshaft position sensor.
