Might check your float lvl on the carb. Had kinda same issue. At wide open throttle, for long amount of time, could be running the bowl out of gas, and it's starving it self. Maybe to small carb?????
I had to adjust my float so would fill all way up. Was only about half way. But that was because put new shocks in back, and changed angle of engine.
Honestly, if brand new. Take back to dealer, and have them figure it out. Would think warranty would cover it.
