Intermittent oven/clock problems

My oven/stove has recently started turning off. When this problem first occurred, I was using the oven and some time after starting to bake, noticed that the clock was flashing and the oven was turned off. It took several minutes before I was able to reset the clock. The screen went blank and came back up blinking again. I was able to reset. This started happening more frequently as I used the oven. Then I noticed that without the stove in use, I would see that the clock would just start blinking and I would have to reset it. There were no power problems in the house-nothing else was blinking (microwave, etc). Don’t seem to have any problems with the cook top. I have an oven that I can’t use, as I cannot depend that it will stay working without interruption. Any ideas??
Thanks so much!

I have a similar problem with a Frigidaire [MODEL]CFES388CCS-3[/MODEL] electric range 10+ years old which we have had since new. It seems to be temperature related - stays on longer between having to reset at lower oven temperatures i.e. with oven set at 350° it stays on longer than at a 400° setting. I think its a clock problem but of course Frigidaire doesn’t stock any parts like the clock anymore for this model and has no idea of a similar part that would work. Nothing else wrong with the range but have to buy new due to lack of a $100 part
