My Panasonic over the range microwave stops after 3 seconds, and turns timer off as if cooking is completed. It occasionally (rarely) works properly for a short time, then goes back to turning off. Any ideas on how to fix this? And where can I get a diagram of this microwave, so I can find the fuses, etc.?

If
it stops after 22 seconds, that means the controller has detected a
problem, usually a problem with the inverter,
controller, magnetron, or a bad connection from one or the
other. If it stops at 16
seconds and is a sensor model, it probably has a defective humidity
sensor.
If
it stops after 7 seconds, it has a problem with the inverter. If it stops at 2-3 seconds, see if this describes
what's happening:
Put
in time, push start and unit runs
for 2 seconds, relay clicks, unit goes off. Cook time on display goes
off and clock time comes back. Bad upper interlock switch and charred
connector
Otherwise, if
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.
It may be a loose connection in the wiring between the
inverter, magnetron, and/or control board, or maybe one of
those
components has failed.
Due to the lethal
voltages used and produced in inverters, I do not recommend that an
inexperienced person work on these.

Our technician suggest that there may be a problem with the Inverter Board in this model, which is something that would need to be looked at by a Service Center.
My panasonic microwave model # NN-S540BFW stops after 4 seconds after you hit the start button and cuts off on its own. What is wrong with my microwave?
From my research, this sounds like a fairly new model. Consult your user's manual to see if this is a user, or common issue. If nothing is descibed then I would seek possible warranty service, or dealer replacement
Mine is the NN-S960BC and it stops after 5 seconds no matter what I set the timer to.....even the sensor reheat buttons.
