Default Random boost cutout???

Car on occasion likes to cutout at high rpms. like it hits fuel cut or rev limit and stops making power. just wondering what it could be??

may not be after it warms up necesarly, just after i boost hard. would a bad plug gap cause it?? What are the symptoms of boost leak?? would it cut off quick and pop? And boost wouldnt stay building and would instead cut??

wrong, im running a maf setup and it will boost with a boost leak, i had a 1/2 inch hole in my manifold and i still made 10psi, it spooled a little later, didnt have any vac, and wouldnt idle for ---- but it did make boost.
