Vehicle shut off while making a turn, started right up without difficulty. Stepped on accelerator to speed up, engine bogged and no power. Gas pedal release restores power. At 2,500 no power.

I would first check the air filter and then change out the fuel filter. Here is a generic guide to help you step by step with instructions in the diagrams below to show you how on your car:

and

If these are okay let's check for a clogged exhaust system, this guide can help:

Check out the images (below). Let us know what happens and please upload pictures or videos of the problem so we can see what's going on.

Thanks for your input. Ran to parts house and replaced MAF sensor. OBF showed MAF and Knox. Runs like normal with replacement MAF.
