last week i had my car in idle warming up than the car turned off by it self ,i tryed to start it up but i wouldn1t start than after few min it start and ran good like it use to ,but since than the same thing happened again the car stall and start back up after a min or so also some time whene i1m driving the rpm will drop to 0 for sec and go back to normal but if i'm driving slow the car will shuttoff but it will start back up after few crank's or a min after .i know the gas pump is not the problem .i did a tap on test on all the ignition and senors parts but it wouldn't stall whene i stop over my mechanic shop .
please if u know what the problem can be let me know soon .

Probably the ignition module. they're notorious for doing that on those old fords.
