Sounds like the fuel filter is getting clogged. It will flow enough fuel for normal driving, but can't supply fuel for full throttle acceleration, causing the engine to bog down. Replacing the fuel filter with a new one should fix the problem.
try replacing your fuel filter, With big temperature swings this time of year, condensation (water) forms in fuel tank, Prior to changing fuel filter run a bottle of STP gas treatment or a good injector cleaner through it.
Is it a possible transmission problem? Does the car start out in 1st gear? ....maybe it is starting off in 2nd or 3rd and kicking down into 1st once you get rolling? Try and feel or hear if the RPM increases when you get the power back as it jerks.
You might try a TPS switch. It should set a code but yours did't. The throttle position sensor sets the spark advance and fuel flow to match. The other possibility is the EGR system which also should set a code.
If you have not changed the fuel filter,try that because if you accellerate hard the fuel slooshes to the back of the tank.
In normal driving the contaminents lay on the bottom of the tank.
Your fuel pump or your catalytic is plugged. have it tested with a infrared gun it will tell you if the cat is bad and if it is replace it test the fuel pump for fuel rail pressure it should read 50 psi then hold to 20 psi for 1 minute.. Also check to see if the intake plate is dirty and if it is do a top engine clean, buy GM's top engine cleaner and run it threw the engine, if you have carbon buildup the compression and cause the car to run bad and the knock sensor will not be able to adjust time. I know this sounds silly but these three things will cause your problem and so will a bad fuel filter.
