Panasonic NN-SA651S Button Issue on Touchpad

Microwave was working fine in the morning and afternoon but went to use it at night and the buttons weren’t working. It doesn’t register when you hit the buttons. Only the stop/reset button works, it makes the beep noise when you press it, but nothing else works. Plugged it in and out, no change. Switched outlets, no change. On the display is shows 00:00 and when you hit stop/reset it looks like its working fine ( the display is normal looking _ : _ ready for you to type in your amount of time) but after 3 seconds it goes back to 00:00. First time it did this or gave any other problem.
Not sure whats wrong. Need help. Thanks.
