SR20DET Cuts Out

I am stuck and could use some help.

S13 SR20DET
550cc injectors
z32 MAF
s15 turbo
Power FC
255 fuel pump

Went to tune the car, when i'm wide open throttle the car will randomly cut out. Boost drops into vacuum, and AFR's don't change. It does it at random RPMS, but only when full throttle. I can hold my foot to the floor and it will remain cut out, until I come off the pedal and get back into it. I can creep to redline partial. Can't do it full. At idle I can rev the car to the moon. Only under load does it do this.

The tuner says everything looks good on his end, no sensor failures or anything out of the ordinary. I swapped in another AFM, as well as added multiple new grounds. No fix.

check the plugs...to much gap can be blowing out spark...many buddies have had oil leaks that cause continuity issues from coil to plug or coil pack going out...
