Re: Engine cuts out !!

A problem like this can have several reasons. It seems to be temperature related, so could be a sensor problem (such as the crank sensor).
PCM = Powertrain Control Module. This is the electronic controler for the engine and sits in the engine bay on the firewall close to the right fender. It has 3 connectors with a lot of wires on each.
But before doing anything, try the keydance: ignition switch off/on three times and leave in on at the third time. The odometer will show DONE when all ok or a fault code. Let us know what you find.
