WOT miss when HOT

My RV12 with the 912ULS will not run smooth at WOT or get T/O power after it's HOT.

Thanks for your responses. I flew this morning and the pressure was all over the place after flying for about 30 mins.
I'm going to order a sending unit and go through the wires when I change it.
