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?
