Fold.

The unusual is common is PLO8. While it appears unlikely that he has AA, I've been stacked in this exact spot enough times to give it respect. I think the best thing you can do in these situations is follow your reads. The action is saying he's got a big hand. Assuming he's not an idiot, you're either splitting with AQ, slightly ahead of A23x/A24x/A34x/high wrap, or crushed by a set. Tough fold, but I think it's correct.

my standard play would be to fold here... but i certainly deviate from that occassionally based on reads.

This can be a tricky spot--sometimes the button will be trying to isolate the shortstack with a mediocre hand like TJKK or something. However, barring any reads that the button is a tricky player (and depending on your mood / recent hands with this guy) I think it's a pretty easy fold.

By the way, if you're going to continue, you might as well shove---there are virtually no cards that can come off the deck that you'll be happy about (9's only, 6s-8s aren't a disaster but you still know you're playing for half the pot very often).
