Oven comes on for 5 min then shuts down everything even the keyboard

Same problem here on JKP15WOW1WW. The cycle starts like this:
1) Open circuit Breaker
2) Open oven panel and push ribbon connector to ERC. Replace planel.
3) Close circuit breaker
4) Run to oven, notice clock flashing some time but not 12:00 and start Bake. Bake button beeps and starts bake coil.
5) Within 5 minutes hear a beep and all buttons on panel are unresponsive. Bake continues. if oven light is on it continues to glow. Only button that responds with a beep (and not to clear bake or oven light) is Clear botton.
Rinse..wash..lather...repeat...
