ignition cut problem -help!!!

[SRdave240]

I have been having this problem for a couple of weeks and can't seem to figure it out myself.

Car runs excellent 99% of the time. But when I really get into it at the higher revs. Then all of the sudden it will completely cut out. I hit a wall. Boost drops to zero and the car will not rev. It does not die though. If I take my foot off the gas for just a second, it will start working again just fine. If I leave my foot on the gas it just sits there - doesn't rev and doesn't boost. I think the ignition is completely cutting out all at once. If I turn down the boost it still does it but will wait till higher RPM's. It also does not do it on the first couple hard pulls and it never does it in first gear.

I'm completly lost on this one - HELP!!!

btw, here is my set up...

Have you checked your plugs?

I recommend Bosch F5DTC. The rest of the world seems to have a boner for NGK. Whatever plug you end up with, gap it at 0.028 or lower.

I run NGK BKR6e gapped to 0.027. I tried new ones - no luck
