This is also an issue, surprisingly frequent, for persons with Narcolepsy and Cataplexy. So many times the food was burned, and way too many times also, I have managed to regain function/wakefulness in the nick of time before fire resulted. Sad to say my only cooking resource is to 'nuke' everything.
Does anyone know of a 200V relay with adequate Amperage rating to set up as a timed "kill" switch for electric stoves?

Get a 40a SSR.

That will run directly off of a solid state timer like a 555 or you
can run it off a wall wart plugged into any small spring wound timer.
I had one on our cook top when our daughter was learning to use the
stove. I used a 15 minute spring wound timer.
