I've never run into this before:
Riding down the road, smooth running, no issues. Suddenly it's like a hiccup almost. Just a momentary loss of power. As if it shut down for half a second. Literally just a blink.
You say a loss of power, is it just the throttle power that drops out, or does the bike actually shut off and come back on? Do you see the headlight go out or the speedo dive and come back up? Any warning lights that come on, even for a second? Does it happen after you hit a good sized bump in the road?
Off the top of my head, I'm thinking that if your kickstand is a bit loose and it happens when you hit a bump in the road, the kickstand kill switch may be causing the bike to shut off momentarily and then it is just restarting itself on a push start, like you popped the clutch.
If your bike is FI, probably loose fi connection under tank..i had same issues on trip ti Ke West, when i got back to Indiana, I lifted the tank on the back, disconnected all the electric connectors, reconnected, and no more issue, that was over 160,000 miles ago.
