Ford special service message 20619: PCM shuts down on 1 hour timer when open or intermittent circuit faults are present or when egt sensors are disconnected. Disconnection batteries will not erase the codes or fix the problem. If the problem is not fixed the PCM will go into another 1 hour shutdown when key is cycled again.
