Hi everybody,

I was facing a similar issue. For me, this was with a stand-alone keyboard. (A Microsoft Sculpt Ergonomic Keyboard). It worked normally for a few minutes after it was power cycled. Then after 5 minutes, the keyboard would be dead, even though all the drivers were working as normal, and there were no error messages. 

The problem turned out to be one of the function buttons at the top of the keyboard. The F9 key had been pushed down in such a way that it was not popping back up. The button doesn't do anything normally, so there was no sign that anything was amiss, but, after some number of minutes, the keyboard would shutdown entirely.

Once I pressed the key, it popped up as normal, and the keyboard was working normally once again.
