2007 XB12Ss, about 4300 miles. Recently, when restarting the bike when it's fairly warm (I can still feel heat from the cylinders) the check engine light has come on, the bike died, the gauges do full sweeps, and the clock resets like the battery was disconnected. This has happened twice, and like I said so far only when it's warm from a recent ride. Any ideas? Thanks!

Check your ground points.

There are several ground points in the subframe, AND a biggie is where the subframe meets the frame.

This sounds like a broken wire in the main harness. Poor grounds usually show up in other ways.

There is an updated wire harness guide up near the steering head. I would have the dealer check to see if it's in place. Also, see if the bike does it when you run the fork from lock-to-lock.

Typically this happens with a broken wire, and it resets everything when the bike goes from "parked on the sidestand and steering to the left" to "started, stood up, and straightened out"

Is it under warranty?

Remove, take a wire brush to, and replace your positive and negative battery cables. Takes 2 minutes, might be the cause of your woes, and even if it doesn't it's a good idea! ; )

Both times have happened when the bars were straight, not lock to lock or anything. Like I said, it's only happened when the bike is warm, never when it's been started fresh, no matter how long it's run. Both times were only after it had been run, shut down, and restarted within 10 minutes of the last shutdown. Of course, trying to duplicate this in my driveway has failed. All the cables are tight,everything's clean, and it's always inside the garage. Between this and the rocker box leaking, I'm disappointed. My UJMs never had problems like this...

I've worked on a couple of (don't jumped down my throat for saying) Harley's that had this type of problem and it ended up being a system relay. Replace and see if that helps you.
