Default air recirc button turning off on its own?

Yep. My 2010 has done this few times. A/C on, recirc button on (lighted), and then I feel the air is not-so-fresh, and I look down, and the recirc button has turned itself off. Anyone else seen this? Why? I *think* that once it happened when I got on the gas hard...might have happened at the same time? What would cause this? Does it auto switch off under hard load?
