2011 f150 ecoboost. I went to pass another vehicle, when the truck down shifted it bogged way down finally picked back up and was ok. I did it again and the same thing happened again.

 

Any fault codes present? Does it sound like the turbos are engaging? I've had a few ecoboosts where one of the turbo to intake tubes was a little loose causing the forced air out the system which feels like the engine bogging down.
