Reduced power engine malfunction randomly?

So sometimes mainly in higher gears my n54 starts stummbling badly The check engine comes on and it says reduced power engine malufunction. All i do is restart it and its fine, as long as i dont get into the throttle alot

Does this sound like the HFPF? It does it so randomly its annoying. Other then that it runs fine and with my Jb4 on map 0 it never does it, but on map 2 it will from time to time

Iike today it was running fine, i did some 3rd gear pulls with no issues

I searched and someone else had the same issue but it was a vacuumn line. But mine comes and goes

Its a 07 335i coupe with jb4 dci 3" d
I need a E60 M5 already
