Do not call the raise. The most likely scenario is your a coin-flip of losing all your chips or you become chipleader. Since your already 2nd, being chipleader is not much more of an advantage vs busting-out of the tournament with a medicore hand. Even if you had a 80% advantage (e.g. QQ, JJ, preflop), you dont want to risk all your chips unless its with a small stack.

These type of hands (wtih 4ppl left) are good for limping (folding is also a good choice) and maybe for a button or SB steal. The mindset should be to wait out the shortstack on the bubble or as a lesser alternative, to play against the shortstack since you have the extra benefit placing in the money if you win. You possibly could risk all your chips with AA, however I think its debatable w/ KK in this situation.

Another comment, I normally dont worry about winning, just placing. I found very often that once you get into the final 3 your odds of winning is still good even if your 1/3 of the chip leader. One double-up would put you on even ground with the chipleader. If you play to "win" you might tend to take early risks with your chips and quite often will bust-out more than you need to.
