konk out
Quit working abruptly
To konk out is to fall asleep suddenly or become unconscious, often from exhaustion: I konked out on the couch before the movie ended.
It also means to stop working or fail, especially of machines or engines: The car konked out on the highway.
The phrase suggests abrupt, unplanned cessation rather than gradual decline.
