About 12 years ago mine would do the same thing under load. I had decided to replace some things do to mileage( Timing Chain,Lifters and new Ford NOS Heads) When I picked up the Distributor that was in my car of off the bench to hand to the tech that was working on my car. We discovered when we spun it it didn't feel right. You may have a worn out Distibutor due to the Mileage.

Dear Friend ,
Is the car fixed ?????

I realize this thread is old, but I'm replying because I recently had very similar symptoms on my 1991-powered car (started happening more and more, but only when the engine was warm). In the end it was the TFI module. Need to be sure to put that heat sink grease thoroughly on the back, otherwise there's a good chance even a relatively new TFI could go bad.
