2007 gmc Yukon sounds like a diesel

[Chin_chin21]

was driving on the highway and all of a sudden I lost engine power and the dash started flashing ENGINE POWER REDUCED. So I pulled into a gas station and thought at first my exhaust came off but I crawled down there and everything was there and tight. So I scanned it with a code reader and it gave me:

-Crank shaft position sensor.
-Camshaft position sensor.
-Mass air flow sensor
-Throttle body position sensor.

I replaced the crank shaft position sensor and the camshaft position sensor and it still runs the same.

This is a video of it running:

I pulled the valve covers and the rockers and push rods are in good shape......whats next?

I have no idea what it could be. Someone please help me out!!!!

Wow, what were the codes?

Off hand I don't remember the numbers to the codes I just remember what they ment. I don't have my own scanner and it was almost 7 months ago that I got the codes, I've had it stored since then, now I'm a little better off financially I'm trying to get it fixed
