All of the rear lighting on your vehicle is controlled by the Body Control Module (BCM). You should begin diagnosis by scanning the BCM for fault codes. The fault codes will give you a starting point in diagnosing the concern. You MAY also have a defective BCM.

Accelaration loss of power

I'd have a fuel pressure test done to be sure, it isn't fuel related again. Takes 5 or 10 minutes so cost should be minimal. The other thing that comes to mind is a plugged exhaust. (catalytic converter) Quite possible on a 10yr.old vehicle.
