I don't really get the minraise by the CO.
Original raiser is still behind. If he's really got a hand why not call, wait for the initial raiser to raise the flop-bet, get a call from the BB and so trap both of them by shoving?
Is this supposed to be like a blocking bet: "Scare the initial raiser so that I see a cheap turn card"?

IMHO the flop-raise by hero is fine.
What if the turn-card is a blank and BB or cutoff bets again, this time big? Call again?
I think it's a good idea to find out what CO hast got.

Second CO minraise looks like a hand not afraid of draws since he's laying good odds OOP. Your line (big flop-raise) doesn't look like a draw, more like TPTK/MPTK/overpair/set.
If he puts you on TPTK/MPTK/overpair/set and still raises, what do you put him on?
CO got only $20 left. If he had wanted to push out draws, he should have shoved instead.

I think he's got maybe two pair, maybe set, maybe a very very weird AA.

If he's got less than TPTK and isn't sure about the strength of his hand, he could call your re-raise, wait for a scare card and push.

I think you're beat.
It's a fold IMO.
