While driving loss of power, pedal all the way to floor no revving, why?

Strong possibility is the throttle body. Need to retrieve the dtcs for any clues. But I could fill a 50 gallon barrel with all the throttle bodies I've replaced.

Full scan test required, also live data can be examined to determine throttle response between the accelerator pedal position and the throttle body position .. Too many possibilities .. Got to be tested!
