Oven shuts off by itself

This range is almost 12 years old. I was cooking dinner tonight and noticed that the oven had shut itself off and the clock was not right. (like it had lost power) So I turned it back on and maybe 15 or 20 minutes later noticed it had shut off again. It turned right back on and heated up and I was able to finish cooking without it turning itself off. This is the first time this has happened. Any help would be appreciated.

First I would check for an intermittent power connection. Wiggle the power plug, flip the breaker on and off…

Do you get the same symptom if you cycle the power by turning off and on the circuit breaker? Same result on display? Also, do you get PF on the display in either case?

I did not get a PF. Also, I used the oven tonight for about 30 minutes (from start to finish) and didn’t have any trouble. I will try the other if it happens again.
Thanks
