96 f-150 302 auto 100000+mi. Problem is- at 55 or more mph. Truck will sometimes quit running that is I watch the tach go to zero ck engine lt comes on, i`m coasting. One or two seconds later engine starts back up by itself, down the road I go. Vehicle has many new parts-pcm, ign mod, ign coil, plugs, cap, rotor. The last time it set a code P0320 ign\dist engine speed input circuit malfunction. It was at ford garage 4 days didn't do it for them. Anyone have any ideas?

Truck is currently back at ford garage. When it was there one other time they said it cked out ok. They called me, said two codes cam up, P0320 ign/dist circuit malfunction[is there a crank or cam sensor?] And they said something about checking fuel pump circuit. Thank you for your reply.

Back from Ford garage in sept 16 out sept 25 replaced crank sensor/ign. Stator they told me it`s odd that this vehicle has both, that maybe this happened during the middle of the model year?All I know is it puzzled the hell out of me. She seems to be running ok but i`ve only had her back a few days, sure hope that it`s cured. Thank you for your interest. Please keep this info in memory bank may need it sometime.
