Sounds like a problem in the charging system. I've seen a Gold Wing backfire and die when the alternator quit.
Batteries can "self charge" to some extent, if they are good, which might account for the bike cranking up after a few minutes.
...that be? It did again a day later when I was accelerating, but this time it was loud and it pulled back very aggressively like something was seizing. Then half an hour later (5min from home) all power cut off and the bike just died. When I tried to restart it, the starter motor just gave that ticking sound. After ten mins rest I was able to start it and get home. What could it be? The bike is not running hot.
