temporary boost loss...

I have a 2005 ford f250 6.0 with no mods but turbo back 4" exhaust,

two different occasions i have noticed a loss of boost.

one time I was pulling an empty 18foot enclosed trailer

the other time I had a Dump trailer loaded to around 16000lbs

both times i was pushing 75 mph and it almost felt like it dropped into a double overdrive Rpms were like 1.5-2k... boost dropped to zero pedal went to the floor, stayed zero boost for like a quarter mile and then shot back to about 20+ lbs where it was before the incident. cant duplicate it empty, fuel mileage has been less then usual but probably unrelated

I have no guesses and im praying its a cheap easy fix.
