radio shuts off every 20 minutes

Help!!
Somehow I programmed my radio to shut off every 20 minutes. In addition, the radio stays on after I turn the car off and the key is out of the ignition.

Sounds like the accessory power line to the radio is busted (or the fuse...)
Check your fuse panel to see if something went bang.

The factory radios will run for 15-20 minutes without a key as a comfort thing. I.e. I can get out and run into the shop and my passenger can still listen to the radio without me leaving the key. They can press on and it will run for 15ish mins then shut off. pressing it again will get it to run again, then 15mins off again.

The fact that this is happening regardless of the key makes it sound even more likely....
