Bubble Paralysis - Stars $100

[Shorty35]

I susally dont find myself in this situation, but here i am...

For the past 4 or 5 orbits, the short stack has been folding literally everything and I have been stuck at a distant third. I have been constant at 3X his stack. I have stolen his BB exactly twice, but have given that back when BB has consistently raised my SB completes. Either or both of the big stacks has open raised every hand.

Q1: I am UTG and find A3s, SB can survive for 4 more hands without doubling up; I am at approx 8X BB. Should I push?

Q2: Assume I fold above, Shorty doubles up when his K4 dominates big stack's KQ, and now has about 2.5X the BB, then this hand; push or fold?
