Need Help on 2008 Ultra

In have a 2008 Ultra Classic bone stock. It has just shy of 30,000 trouble free miles. Today I was out riding and lost power. Cruising 65 and lost all throttle response. Engine light came on and it went into limp mode only able to go around 2000rpmwith no throttle response. The codes it gives are P0505; P1511; and P2135. It is not under warranty and I would like to fix this myself, I have the manual. What do I do next?
Thanks for your help,
Zapps

P1511 is EFI power mgmt mode. P2135 is TPS correlation error. Don't see a P0505 on my list. Think these bikes may have an issue with the wiring behind the air cleaner near the throttle body, but I can't remember the specifics. Might do a search on here as I have seen similar problems before.

Shut it down and restarted and could'nt go above 2000rpm. I then cleared the codes, and started it back up and all was OK. Have'nt had any problems since. Have done about 6K miles since that happened.

Now that I think about it, I had the TPS correlation error also. So try clearing the codes and see what happen's

Sorry, don't have anything to add other than to say that I will be watching your thread closely for obvious reasons. Thanks for sharing, I may learn what to do when/if it happens to me.
