It may be the coil packs. It's common fault on these, and it manifests around the 4k mark as you're experiencing.

it could be coilpacks... or it could be afm.. if its a stockish engine.. id say afm..

coilpacks will stuff up on a modded engine, running more boost... generally the r32 coilpacks arent to bad, and they are used on rb26's aswell... the rb25 coilpacks stuff up as they are different.

coilpacks will do it fairly regularly.. and it wont get over 4000rpm. it will cough and stutter as it cant handle the fuel/air required.

afm can drop in and out... i had the problem where as i put my fott down slightly to overtake, the afm would die, and cause me to near shit myself as im in the wrong lane trying to overtake and my car just died, then it picks up again and motors on for 100kms.. it did it at the weirdest spots. replaced the afm with a z32 one and happy days, no dramas.
