Kitchenaid KGRT507B oven shuts down randomly when in use.

Not Sabbath setting or timer. Sometimes it takes several attempts to enter temperature as well. Sometimes it will work perfectly, and other times it takes a few attempts to set the temperature, and then it operates normally, until it decides to just turn off. It will restart after resetting the key pad by holding down the broil button, almost as if it experienced a power failure, but it does not indicate that. Then it will work fine, or freak out again. I'm leaning towards an exorcism. Please help.

Thank you

Upon further review, the touchpad and control board have corroded and brown spots. Both parts no longer available. 23 years, can't complain. Now starts the discussion, "Well if we are replacing the oven, we should do the fridge and the dishwasher so they all match." Wish me luck.
