First thing....check ground...make sure it is clean, not just appearing to be bolted well. I've had connections corrode over time UNDER THE BOLT.....not kidding. Also check for the obvious signs of wear on wiring, etc. Might also check the ecu pins for corrosion, since you said that it happened last time after moving the ecu.
