$55 Bubble: The Minraising Donk

[Taraz]

Hero: ~2000
Seat 2: ~3000
Seat 3: ~3700
Seat 4: ~1300
Blinds - 150/300 and moving up in 4 hands

So Seat 2 was ridiculously tight with his big stack and Seat 3 was minraising 75% of the time. This doesn't seem like the worst scenario except for Seat 3 called a stop n go with A hi and called a push over the top from the blinds w/ QT (for 3/5 of his stack).

How do you play this scenario if you don't get cards? I didn't want to tangle with the minraiser because he's not folding and I was pushing when he folded, but is that enough? If I have something like A5o and he minraises my blind should I push knowing he'll call any two? I was really confused about what my plan of action should be here. Any ideas?
