pulse adrenaline, cutting out issue.

Hi I'm new to the fourm. I have a pulse adrenaline. It's a 12 plate done 3500 km. Been great for a month. Riding to work this morning noticed the gear indicator was dull and the lights. Next thing lights went off completely and the bike died. Tried to bump start it and nothing. Pissed it home. About 2 miles and put the battery on charge for 2 hours. Put it back in and started fine. Voltage going into battery was 12.5-13, took it for a ride and same thing happens. Any ideas. Thanks. Matt.

Was the battery discharged again? Might be the Reg rectifier. other than that you're looking at the stator or wiring in that area.
