From what you describe, it sounds like you may have a mass airflow sensor problem. Are there any codes, check engine light on? You could try cleaning it. There is a spray cleaner available for that application.***** The mass airflow sensor (MAF) measures the amount of air entering the intake feeding that data to the ECM. This is what decides your air/fuel mixture. If the air reading is off, it could be causing your bogging issue possibly running too lean.

I agree, the MAF sensor sounds like a possibility here. Any codes?
