This sounds like a binding servo problem. On the earlier launch, the power bus may have been pulled down by the overcurrent causing the momentary control lockup you described. Releasing from the winch may have released the bind allowing the resumption of normal control. This reasoning continues that on the later launch a repeat of the bind caused an overcurrent that blew the circuit on the switch board which was damaged by overheating during the earlier overload. Just guessing.
An onboard battery checker may have helped to disclose this condition in advance if you watched it while exercising the servos and possibly loading the surfaces by hand on the ground prior to flight.
