Strange Power Loss

Strange Power Loss
I just got back from a ride where I experienced some power loss at highway speed (70-80mph). At first, I thought that I ran out of gas and switched to the reserve. The power loss continued. It felt like there wasn't enough gas getting to the engine. I would twist the throttle, but it didn't seem to work. The engine didn't shut off and it idled fine. I couldn't get above 20mph and 2nd gear. I found a gas station and filled up the tank. This seemed to work for a while. Again, at about 75mph I experienced the same thing. I pulled over and looked for anything I could see that might be wrong. I couldn't find anything. I slowed it down a bit and kept it between 50-60 depending on the road, and it seemed ok. I know very little about engines and Harleys. What are some things I can do to find what the problem was? Lastly, about 20 minutes after this all happened, I was back up to 70mph and didn't notice it. Please help!
By the way, I have a 2006 883 custom, all stock.

Check for DTC's (diagnostic trouble codes), there's a Sticky at the top of this section if you don't know how. If you have a P0373 or P0374 code, you have a bad Crank Position Sensor.
When you have a bad sensor, turning the motor off and restatring it will usually clear the problem, temporarily.
This is a common failure item on 04 and later Sporty's and the symptoms are exactly as you described.

For earlier years, the P/N is 32707-01B.
The sensors are the same except that the -01B model has a 4" longer cable.

So I checked the codes and this is what I found:
P: none, Part # 32889-04c
S: b1121, b1122, u1255, Part # 68920-01d
SP: none, Part # 67436-04
T: no response
I cleared them to make sure they weren't old codes, ran the engine for a couple of minutes and tried again. this time "P" had no response and there were no error codes under the rest. I took it for a 25 minute ride on the highway to see if I could replicate what happened yesterday and it seemed to be fine.
My question is, should I go ahead and get the sensor replaced? Also, do any of these codes and part numbers mean anything that I need to pay attention to?
Thanks again.

All was well until a couple days ago. I went for about a 65 mile ride on some back roads. At about mile 40, going roughly 55 mph, it happened again. This time, I just down shifted and slowed things up a little bit, and it stopped after about 30-45 seconds. The rest of the ride was fine. I checked for diagnostic codes afterward and none came up. Anything else I might check? Thanks again.
