My 08 Night Rod has been acting up lately and I was wondering if somebody had any suggestions. It is stock except for Tab exhaust and Tab fuel manager. Recently it started cutting out randomly. Acting like something electrical cuts off shortly and then acts fine. It doesn't shut off but power is lost for about a second. It did it four times over a 200 mile trip. Now I can't get it to do it (haven't tried a whole lot more) but the check engine light comes on for about 10 seconds after the bike is turned on and goes off. Could this be a problem with the fuel manager. Thanks.

My bet is on the fueler’s connection to the fuel injector…

You are probably right on the IAT sensor. I believe that is the one connected to the air box. I started the bike without it connected once and the light came on after that. I reconnected it and it went away initially but would come on for a bout 10 seconds after the bike was running then it would go away. Was that to let me know there was a historic code in the system?

You have a historic DTC stored. You need to clear it (explanation of how to do this is here) or the CEL will keep appearing for 8 seconds after the initial 4 second illumination after turning the ignition on. Or you can wait for 50 good “ignition cycles” for it to clear automatically.
