Why does a 1987 Chevy Celebrity start up and run for about 10 minutes and then die and wont start for about another 10 minutes and then die again?
I had a similar experience with my 1987 Chevy Celebrity. In my car's case I replaced the ignition module and the crankshaft position sensor. Between the two the problem seems to be fixed.

How do you Check 1987 Celebrity crank position sensor?
To check the crankshaft position sensor on a 1987 - 1990 Chevy Celebrity: 1. Set the parking brake. Raise the car as necessary and put on stands so that you can get to the underside of the engine at the ignition module. 2. Locate the wire from the crankshaft position sensor to the ignition module. It should have a yellow and a purple wire. 3, Measure the resistance between the two wires. It should be between 900 and 1200 ohms. If it does not read that amount it is probably faulty OR you have a problem in the wiring. There can be a problem with this though. If the sensor is good cold it can still be faulty when it gets hot. The ignition module itself can also have the same problem. If you put on a known good sensor and the problem goes away, then the sensor was probably your engines problem. WE have a car that would run fine until it got hot. It would then quit running and not start again till it got cold. We replaced both the crankshaft position sensor and the ignition module and the problem WE were having went away.
