I had a similar issue not long ago. It happened most frequently when the bike was in stop and go traffic and when sitting at a light. This pointed me to the charging system. I tested everything. The charging system seemed to be fine. I checked the stator output, the battery was brand new, regulator seemed to test fine under load and at idle. I even went to great lengths to make sure all connections were tight and had a good amount of dielectric grease on them.
Well, long story short, I replaced the regulator with a Cycle Electric unit and my problem disappeared. The regulator seemedfine when running charging tests at idle, but once I was moving and the bike was hot, it was crapping out. The stock unit isn't very good. Cycle Electric makes a quality replacement.
Start simple. Check connections at all terminals and make sure they're tight, especially at the battery ground on the frame. If that doesn't fix your problem, I would say to test the stator or regulator. In my case, it was a deceiving regulator.
