3rd gear 2500rpm to redline

Fuel low pressure jumping up and down, rail pressure dropping at high rpm. Slight misfire in the middle of pull, but no codes.

Hey guys I really need some help figuring this out. My car gives up power when wot. It mostly gives up in 3rd gear however does happen in other gears as well just not as often. It loses power at around 5,000 rpms when doing pulls however in normal driving it does not. What can this be? I was doing a pull today actually and went through 3rd but once I was in 4th it gave up around 4,500 rpms and I got a epc light. Please help!
