Sharp Power cutoff at 5000 RPM

[SomeAircraftMech]

Help me guys/girls, just noticed this yesterday. Was doing a bit of spirited driving all AP info was normal no CEL, when out of nowhere at 5000 rpm it felt like I had hit the brakes for a second, a sharp power cutout in 2nd gear. Being curious I tried in 3rd and 4th while under WOT it would sometimes do it at 4500 and 5-5500 where it would dump all power and jerk like I had hit the brakes. Still no CEL. Tried under normal load and didn't do it. Only when giving it the beans. Relative manifold and boost press both showed the correct 28.7 psi as normal. Otherwise car runs and drives normally. Pulls great all the way up to that RPM Ran codes again to verify and still none showed up.. Car is 17 GTI stage 2 EQT 93 Oct, NGK step colder plugs, APR red coils, FMIC, yada yada. Tried to do some research only recommendation was crankshaft pos sensor. Any information of verification would be greatly appriciated.

Datalog it and then report back.

It's datalogged. Not sure what to make of it though. Foot was to the floor but accel pedal showing max 74

Can you check your wastegate voltage with the engine off and the key on?

Can you share it?

Share your datalog via datazap, will make seeing what might be going on much easier. Upload multiple pulls of possible.

This is pump gas?

Yea 93, from the same place I always go

 

[Diggs24]

Plenty of gas in tank? Either hpfp or lpfp is bad.

You are running out of fuel, unless your tank is empty there is likely something wrong with the LPFP, dont think it is the HPFP since it happens mid RPM and more progressive.

Full tank of fresh 93, so no go on possible crank sensor?

 

[Diggs24]

You have a crank sensor code or just google some stuff?

Nah when I was searching forums I found someone with a similar issue who ended up having a cps issue that supposedly fixed it. Said he didn't have a code either. But the lpfp seems more accurate.
