Hi Hassman

I would ask few questions, 1) does the car only stall after driving awhile, 2) have you let it run for a long time at home, and 3) was the hood up at the time you were watching for the stall to reoccur?

One thing I discovered about CKP (Crank Position Sensor) failures of that era is that they typically fail under high heat soak situations. Condition: engine at operating temperature usually while driving, but raise the hood and wait for a stall and it seldom dies. Close the hood and allow the under hood temperature to increase and poof, it dies. At the time it stalls you can test the CKP for an AC voltage signal, >.750mV (over 1V is best)
