It happened to me, it is the corroded conector behind the air breather. Dealer put new pins on connector and it has been fixed. I am an electrical engineer and I understand the failure quite well. There are two sensors ( Hall effect sensors) in the new fly by wire throttle. The computer reads the sensors which both must indicate the same position for redundancy. The sensors connect to the computer via a wire that travels thru the connector I mentioned. When a corroded pin causes an intermittent disconnetion the computer see different position indications in the throttle and shuts down in limp mode. This is ususally an intermittent problem so this is why you are able to power down and up an go, but it will happen again unless fixed. It happens at around 20 to 25 K miles.

I believe there is a HUGH lawsuit against a HD dealership over this same issue.
Rider was given his bike back and was told that the dealer had fixed the problem only they hadn't.
If memory serves me correctly, I believe he was a M/C cop.
Anyway he was killed due to the fault not being fixed in the throttle set-up.
Beware....

it happened to me the 1st week i had my bike. it ended up being the ECU connector not being tightly fastened under the seat. my bony *** caused the connector to come un-done. It was VERY common for the 08 touring years. whomever set up my bike didn't fasten things correctly.

Ditto on this I've had just about everything replaced including the wiring harness and guess what It still did it (go into limp mode)
The connector pin behind the AC is the colprit Simply spray that with some contact spray or anti corrosion and that is the trick man... Hasn't happened to me for a while now.
