Flight Aware's log for Saturday's flight also shows a gap from 1:44PM to 2:33PM Eastern. It was likely over Mexican airspace during that time. How far can a 757 get in 20-25 minutes? 200 miles isn't out of the question.

According to the main page for the flight, it took 1:31 to fly. At 500 mph, that would be 750 miles. Of course the initial climb and descent were slower.
