Fold AKo Preflop?

[666]

Just a theory question for you guys:
If you have AKo on the button in a six-handed game and UTG raises, #3 reraises, and #4 caps, are you going to call? (Assume #3 and #4 are TAGs)

Just wondering because the situation came up in a game I was playing today and I folded AK. #3 had AA, and #4 had KK. In this situation it was a good fold, but that is very results orientated thinking and I was curious as to what the proper play was.
