This 59-second stop failure is due to a problem in one of the damper-related components, most likely the switch, but it may also be the motor or the damper door.
The damper is a door inside that opens or closes depending on cooking mode. If the controller thinks that the door is not in the right position, it will shut down the cook cycle.
See the attached sample photo.

SOURCE: I have a panasonic NNA883w
the digital programmer circuit / controller does not get a feedback
signal from the inverter for a period of 3 seconds, the controller will
stop the cook cycle.
Due to the lethal voltages used and produced, I do not recommend that an inexperienced person work on these inverter-based models.
