Throwing codes at WOT?

My car is running Cobb stage 2. Scoops, drop-in filter, AR downpipes, HPF exhaust.
I'm on the stage 2 drive map. (Cali octane)
After a few pulls my car will show a half engine light and a loss of power. It's happened twice in the last week and I didn't have my AP hooked up to read the codes.
If I park for a minute a restart the car it's fine.
Any ideas?
