While driving, car lost power. This happened a couple of times and then it shut off. Got new catalytic converter and drove home but the next day, it happened again. This time they said it was the fuel pump. New fuel pump, the next day, it happened again. Towed again and told it was the distributor. After new distributor, distributor cap, plugs and wires, the same problem. We are out about $1,000.00 and the car still has the same problem. Seems like it will start after sitting a while but is going shorter periods of time before shutting off.
Do you
have the same problem?

This sounds like an IG relay or ignition switch is heating up and failing. Here is the location of the relay. Also, check for power through the ignition switch when the car stalls.

Check out the diagrams (below).

Please let us know what you find. We are interested to see what it is.
