50+5 Level 2, AK facing a large raise

[BadMongo]

I really hate facing a big raise early on with AK and AQ, especially out of position. I know what I would do here if this was a lower buy-in game, but I'm trying to make adjustments for the 55s so I'd appreciate some feedback. I don't like my options here - I can see arguments for folding, calling, or pushing.

So what's your play and why?

Reads: UTG+2 is loose and has limped almost every hand, and MP2 seems pretty solid and had not raised up to this point (I think he played one flop from the blinds so far).
