Anybody had a complete and abrupt electrical system shut down that could only be corrected by disconnecting and reconnecting the battery?

Possibly the electronic ring, surrounding key or push button
Being a 15 I would hope it's a BMW problem under warranty

Not had that one.  Doesn't sound good though!

Ring your dealer NOW.

I considered the ring around the push button, which I understand has been a problem in prior years. The bike is under warranty, so I took it to the dealer who hooked it to the diagnostics, but no fault codes were found. I expected that disconnecting the battery would clear fault code memory however I asked a service tech at Max BMW if the codes are erased when the battery is disconnected and he said, "no." If that is true there should have been a DWS code (or something). What puzzles me is the abrupt nature of the problem. When the engine died the dash display (all dash lights and the information display) turned off. I pressed the keyless ignition button and for a moment the display lit up and the speedo and tach gauge needles went to 120 mph and 7,000 rpm, respectively. Then it died for good however the gauge needles remained at 120/7,000. It was as if the CPU started the system test and then froze.

It's been a while since this post was updated. This really sounds like a loose connection at a battery post. Any updates/fixes provided, or has the issue represented?

I recently experienced the same issue, I dropped the bike in gear while having the kickstand down. All systems went blank. I checked fuses they were good (surprised to see only two). It was totally dead, no horn, no lights. It's a relatively new bike, few months old. While enjoying 3k miles. So I checked the battery and as someone alluded to it seemed as if the battery lead was only finger tight. So I tightened it and I was back on the road! So far, no repeat (200miles).
