Axys cutting out ?

[damx]

First thing first 16 axys. 240 miles about 17 hrs. All stock but clutching. Sled was running good all day but near the end of the day when climbing about 15 second full out sled would miss about 10 times back to back very fast.. rpm was 8300-8350.. never lost much rpm was doing it so fast cutting in and out. Tryed eth mode. 8150-8200. Same thing.. any ideas?

So figured out at about 1/4 tank left of fuel is when it starts cutting out.. I fueled up to just over half tank and it goes away. Back down to 1/4 tank and starts cutting out again. Also after a climb rpm stay up around 4000 rpm. It's at the dealership now, hope that it gets fixed.
