I've been thinking about fuel starvation too. i may put a fuel pressure gauge in just to check. i have a 5500 rpm chip in right now, i'll stick a 6000 chip in it tomorrow just to make sure. i'd be shocked if it's the rev limiter. I've heard the msd rev limiter cut out an engine before, where you could still hear the engine, but this is just completely cutting off the engine with my foot still in the gas. that's why i'm totally stumped on this one.
