I did , happened to me while trying to accelerate in 2nd gear.
The bike was, very sudden, simply shut down, the whole system, no engine, no lights, no electricity nothing.
I stopped turned ignition key and like nothing happened.
It seems like a bug in Ignition switch , it does not properly locked, it is something dangerous and seems like recall needed.
It is the first time it happened to me with European model MT09 Tracer with only 6000 miles.
