1997 Ford F-150 remote lock control causes CAB electrical to

When I use the remote key entry to lock or unlock the doors, the interior electrical system shuts down. Everything from ignition, power windows, dome lights, everything except for the cigarette lighter outlets x 2. I can turn on the headlights and everything resets as if I disconnected the battery and reconnected. Clock reset and radio memory also. The last time I used the remote fob to lock the doors the door lock mechanism went into a stuck locking mode( clicking noise continualy locking) would not let me unlock with fob so I used the key and it stopped making noise, but again everything was shut down including ignition, etc. Turn on headlights and everything back to normal. Except to reset clock and radio memory as explained. Any ideas? Bill
