Dennis,

My guess is the head gasket, but you could have also toasted the plugs, coils, or the ECU could be stuck in high temp mode where it is shutting down fuel flow to keep the engine from over heating again.

I get a similar thing when my AC fan kicks on when I turn on the AC. The engine lugs down and there is no low end power.

Hope for the best for ya.
