2011 Te250 Fuel Issue

Hey everyone, I have a 2011 TE250 that has the fuel issue. Has anyone actually pin pointed the problem? I've heard its the injector, relay, fuel pump, fuel filter, ecu, and emission issues. What is the actual problem? Does anyone know? I've replaced the fuel pump and filter. I don't want to spend almost $300 for an injector if that,s not the issue. The bike tends to cutout when its been ridin' awhile. especially when trying to get up a hill, it just doesn't want to go no matter how much throttle i give it. I've been told that getting a power commander can help the issue. The local bike shop told me they won't work on red tops any more. So I'd like to figure it out myself if possible.

I also can't find a shop in the area that will even work on it.
