AK Problem

I play it correctly before the folp but get in trouble after. when the flop board isn't to terrible I will bet if I raised pre flop, and call a moderate bet if I just called pre flop. My problem is this; if I flop an ace or flop two pair, It's hard form me to get away. Any suggestions. I play mostly MTT's and have gotten knocked otu a few times b/c of this hand. Have also doubled up a few times.
