You're faced with calling 46.5k into a pot holding 71k, so about 1.5:1. It seems like the key question is whether you can reasonably assign him a range that's wide enough to call after factoring in whatever value you put on your tournament life at this stage.
This is player-dependent, but with no info on the opponent, I'm inclined to fold. The fact I have AK does reduce the likelihood he has AA or KK, but otoh, how often am I ahead? Seldom? Never? If I decide it's either of those, then I'm putting him on pocket pairs plus an oddly played AK. But can I assume his range includes enough pairs to make calling mathematically correct given the pot odds
Even if it is, it seems close enough that factoring in some value for my tournament life and the fact I'd still have a playable stack nudges me toward folding. Plus I'd probably have raised somewhat less, which would mean the pot odds
to call if he still shoved would be a bit worse.
