Folding AA78 pre on MTT bubble

I realise this is super nitty and played terribly, but I want to know overall thoughts, 10 left 9 paid, I'm 2nd shortest stack shorty has 1.5bb and is about to be hit by the blinds

Folds round to me, big stack in the BB, I minraise AA78 (suited Ace)

I knew deep down big stack was always going to jam (his 25k to my 7, blinds 400/800)

I folded here, and my reasoning is literally because I have, **** you not, final table bubbled or stone cold bubbled approx 12 mtts in the past 2 weeks with AAxx. I realise that superstition is completely dumb, but given vs most hands unless I have them dominated it's basically a flip is the fold ever OK here?

Given I was sure big stack was going to shove on me with any 4 I think I either: make the shove myself, limp, or fold outright saving chips. I think min raising knowing I was folding to a shove was simply the worst thing to possibly do in that situation, so I'm aware I completely misplayed the hand, but I want to know if in this situation the general fold is OK, or should I just be shoving every single time and taking my equity?

I ended up sun running from 789 chips left to coming 2nd so it worked out for me, but going forward I'd rather make the correct play. I personally find in PLO8 AAxx just doesn't hold up well for me, and really when it's junk other 2, which 78 basically is, I think it's foldable, could be dead wrong though.

Any opinions and feedback welcome!
