When I put something in the microwave, it works for about 3 seconds, then it shuts off and keeps saying to reset the clock. When the clock is reset, I start over again and it does the same thing. Can anyone help?

Two options to try:
a) Press the Clock / Timer button 3 times
b) Unplug, wait a few seconds, then re-plug to power up with the factory settings. You will need to reset your clock and any favourite settings.
This should work with all Panasonic Microwave models.
The problem is your magnetron tube is leaking RF. The mag tube comes on 2-3 seconds after you hit start, and the RF interfears with the board and shuts it down. Drop the front of the control panel down and watch, it wont happen.. Get a new mag tube put in and you'll be good to go.
There's a simple fix for this. Unplug the unit. Take off the top grill with 2 screws. Remove the 1 screw that holds the touch pad unit. Lift up on touchpad unit and lift out. Put a piece of aluminum foil inside a large zip lock bag and tape it to the back of the touchpad unit and reassemble. GE put the magnetron to close to the control board causing stray microwaves to interfere with the board. The foil shields it.
The clue is that you have to reset the clock. You are losing power somehow. the Main Board thinks it is being unplugged and it resets the clock and you have to start all over. The fact that after so many times it will finally work tells me that whatever bad connection you have is finally getting hot enough to expand and make a good enough connection to keep working. Intermittant connections are the worse to find. A lot of trial and error to find the problem. can be bad fuse and fuse holder ( in the unit), bad outlet, loose wire at circuit breaker, loose wire at outlet. Even a loose breaker where it snaps onto the buss bar in the Breaker Box. Etc, it an really drive you nuts trying to find it. Try the unit in a totally different area making sure it is on a compleately different circuit breaker and see what it does, if the problem follows the unit, the problems is in the unit. If not, electrical problems, outlet, breaker, panel,
take the cover off of it and plug it back in and see if you can locate the hissing sound, thats a new one on me. hard to help solve problems online unless u are there with it. something is tripping it out
Sounds like you could have a fauly control circuit. Something like when you press the pad the processor does not interpret the information correctly and resets itself. Or the power going to this circuit is being interupted. It is VERY dangerous to work inside of a microwave. So you could get an estimate from a repair shop. But those control boards are expensive. Do not attempt to repair this yourself. For your own safety.
