Check your CAI bolts and make sure it didn't come loose. I have a JLT CAI and when I leave my car setting for a week it loosens around the throttle body and my car does the same thing. Pretty much it just sucks in unmonitored air in and your car can't accelerate worth crap.
If that checks out to be ok I'd say fuel pressure regulator, you can find the fuel pressure check valve on the fuel rail passenger side toward the front of the engine with a plastic black cap.
