It's the Rev limiter when you are in park. It's doing what it's designed to do. Mine will also not go over 3000 or so rpms in park. This is to keep you from blowing it up while sitting in park.

Try replacing your fuel pressure regulator and fuel pump. If your cat converter is plugged, that will also rob you of power.
