Re: 1991 Olds Reg Elite stall at operating temp

Runs absolutely great until it gets up to around 200 degrees (analog gages so maybe inaccurate), stalls at speed, trys to start but will not until engine cools back down. Right now I will just turn on the heater to pull some heat out and will start back up and run as long as I keep the temp below this trigger point. Several post have suggested the Crank Position sensor. Has this resolved this problem for anyone else? Are there diagnostics for the sensor that I can perform with a meter? Please help as I live in the south and the heater solution is really hurting right now. Thanks
See if you have spark and injector pulse during the event if not the ckps is most likely the problem but wiring to the icm and /or the icm could also cause this.
