I didn't report it here as I have a couple of other issues on the go, but I can confirm that I have experienced the exact same thing. One minute it's working well for days, then nothing.

The only solution is to power off the pi for 5 minutes ( and all attached equipment) and then restart it all.

I have not found any hardware issues that account for it, but unplugging the HDMI from the pi when this happens causes a strange sound from the speakers. Normally there will be a 'click' or 'clunk' sound, but when the sound has stopped it's like a whistling sound that starts high in pitch and rapily goes lower (it reminds me of a balloon quickly deflating when I hear it). Maybe a capacitor discharging on the board (or off board)???

After resetting it can be days or weeks before it happnens again.

Can you tell us more about your set up? (you can add it under your user profile to save re-typing it every time you post).

Strange....One for the X-files!

strange as you said
yours looks like HW fault. But it can be any device in your connection or even the cable or a bad PSU for RPi.
I would start there, try to change the HDMI cable an if not than test the rest
