I get the same symptoms on my bike, especially when riding long distances. After a while I just speed up as fast as it will go while stuttering and pull in the clutch. I kill the motor for a few seconds switch the kill switch back on to let the pump prime and start it on the starter. Then it will pull hard all the way to redline again. On mine I only need to let her "rest" a few seconds and she runs like normal again. She does this on 98,95 and 93 octane fuel at any altitude I have reached thus far. If I ride hard it will happen sooner than when I just sit at the speed limit.
I think its the fuel filter and/or pump. Probably from the sludge left in the tank after manufacturing.
Just my opinion though, but the dealer cant find the faulty code so they cant help me at all
