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.

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

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