I'd bet it's one of your ABS sensors! When I had a bad sensor, every now and then it would do exactly as you describe. Replaced the bad sensor, and no more problems. Is your ABS indicator lamp working as expected? If it's amber all the time, that indicates a problem. It should go out upon first traveling above 6 mph, and then stay out until the bike is restarted.
