What causes the engine to lose power? "Reduced engine power" message.

(2007 Chevrolet Suburban 1500)
in San Diego, CA on October 15, 2013
Out of nowhere my check engine light comes on, and I lose power. "Reduced Engine Power" message comes on and signals that I need to service stabilitrac. Well I took it in and they replaced the spark plugs and wires and reprogramed the throttle body. Well all was good for about 4 days and then the same thing happened. I also have been losing oil a little quicker than usual. When it does happen I pull of to the side of the road, shut the engine off, open the hood to check for any burning or anything and nothing. I close the hood, start it up and it moves on. Not sure if this is a trend with this model. The tell me that I may need to get an engine rebuild but can't tell me why or diagnos the problem.

scan test for codes it could be a plugged cat but if it is engine related I would start by doing a compression test
