Strange Boost Problem

[SYSTEM6]

hey guys im very new to gtrs and i have just bought an R33 GTR v-spec first things first...u gtr guys were really on to something, and secondly some times after ive been driving around giving it abit here and there but nothing major i will lose a portion (be it half or more) of my boost and it dosnt come back untill i turn my car off for like 10mins and turn it back on, It dosnt do it all the time but enough to annoy me. I have hooked it up to a diagnostic software but it said that there were no electrical problems, then i had a good'n'propper look under the bonnet and i saw that the o2 sensor was unplugged so i plugged it back in and it seemed to be fixed , but just now the problem has come back. Ive researched on here and on the net but couldnt really find anything helpful,

thanx for your time any help much appriciated

and i have asked a few people that own gtrs and they have no idea im hoping that some1 on here has had the same problem and fixed it before.

im not the best with cars but i took my xr6 turbo to lmg performance and paul said that cars like these and skylines ect, do this becuase the coil packs get too hot and are in the engine and not seperated on the side like others. dont qoute me on it but you may need to look at this, may be the problem also check the spark plugs i done this and the car ran fine after putting in my new plugs.

maybe your turbo's have gotten too hot and they loose performance until they cool down

check that your O2 sensor plug hasnt shit itself and keeps falling off.
