This sounds similar to what you described, but in a 727 -- written by the Boeing test pilot's daughter:

"And even though my father had learned from past experience to watch this particular FAA pilot closely because of his tendency to pull back too far on the control column, Dad said he was still taken by surprise when the guy abruptly pulled back so hard that the 727 entered an extreme angle of attack—70 degrees rather than the usual maximum of 25 to 30 degrees—what an aerobatics pilot would do to start a snap roll or a spin. Suddenly, unbelievably, they were in a deep stall."
"After losing nearly 4,000 feet in altitude, the wings finally regained normal lift and the 727 leveled off."
"When the flight test data recordings were later analyzed, the angle of attack trace was off the scale. For seventeen long seconds the elevators were full down (control column full forward) and no air speed data were recorded as the 727 simply fell back and down toward the earth, seconds that felt like an eternity to those onboard."
