Check the throttle pedal position sensor on the gas pedal and see if the wiring is loose or pinched. If the wiring looks good and is not damaged, then I recommend replacing the sensor. If you need further assistance with your vehicle loosing power after letting off the gas pedal, then seek out a professional, such as one from Your Mechanic, to help you.
