I have a 2008 and it was running fine. Added an exhaust and power commander. Was running great. One day out the blue it would spudder at full throttle but would run at half throttle. Thought it was starving for fuel so did some tuning on it. Was riding during tuning and it killed and never started again. Have changed TPS sensor, injector, fuel pump, and has good spark. All I have left to change would be the ECU. Has anyone ran into this issue or can point me in the right direction.
