Had something similar on my R1200r some years back, turned out to be a dud battery with one or more cell going open circuit under load. Fine after £80's worth of battery swap!
Had similar on my 1250gs as it had stood with the auxiliary lights / ignition on, I now carry a sealy booster / jump starter which works if I’m a muppet again but also helped my riding buddy out on one occasion, his was actually diagnosed as a duff battery ( from a batch of duff batteries ) by local BMW dealer as his GS is still under warranty, I’m sure he’ll be along soon to chip in his tuppence worth of wisdom though 
And the answer is - 'Battery Knackered'.
Glad you got home OK Bob.

Had exactly the same on my 6 month old 1250 GSA last month, 12.4 v showing but same symptoms even though used regularly. Assist arrived, ordered and fitted a new battery the next day and has run fine since. Duff batteries seem to be common on late models????????
The bikes with Rybrook now hopefully will get a new battery in the morning, I certainly don't want another BMW assist experience.
Further update, having dropped the bike off yesterday afternoon at Rybrook Wolverhampton, they supplied me with a rather nice courtesy bike, tested the battery overnight, confirmed a faulty battery, overnight delivery of a new replacement that was fitted this morning, so well done Rybrook Wolverhampton for a seamless service, as for BMW Assist, I await a response.
