Folding AK to early pushes

[Taraz]

I am routinely calling in these spots at the 11s-33s, but I'm thinking it may be a huge leak. Should I be folding here?

Party Poker No-Limit Hold'em Tourney, Big Blind is t30 (9 handed) internettexasholdem.com (http://www.internettexasholdem.com)

UTG (t620)
UTG+1 (t425)
MP1 (t1750)
MP2 (t1080)
Hero (t1145)
CO (t555)
Button (t865)
SB (t790)
BB (t770)

Preflop: Hero is MP3 with A/images/graemlins/spade.gif, K/images/graemlins/spade.gif.

4 folds, Hero raises to t90, 1 fold, Button calls, 1 fold, BB raises all-in t770, Hero???

Im new to SNG but he has to call 680 to win 875 so hes getting 1.29 to 1, and has to be 44 % to win to make the call worthwhile. Even with a range of TT+,AQs+, and AKo hes 45.7 % to win. Is my hand range not tight enough at the 11's through 33's?

I fold this more as the buyin gets higher. $11s I never ever fold, $22s I rarely fold, $33s I'll sometimes fold and $55s I'm folding about 60% of the time.

I used to make this call but hated gambling this early for my whole stack in a likely coinflip scenario. I also used to make a standard pfr with AK in the early stages and often check fold to a non A or K flop but I started to hate this also. So lately I have been limp/calling average sized raises preflop with AK and checkraising/raising the continuation bet when an A or K flops and folding when it doesnt. My whole motive is to minimize the number of chips lost in the early stages. Not sure if this is a good strategy though.
