Tricky reraised pot situation

[cb4mvp]

At this point I had no reads on this guy. He had just arrived at my table. He went on to 4-bet me twice in the following 15-20 minutes. At first the fact that he 3-bet my utg raise with two callers seemed very strong, but I called nonetheless. I know that if I put him on AA-KK, I don't have odds to setmine. Basically it's a fold if that's the exact range I put him on, right? Anyway, as played, is this a standard fold on the flop here? I've been having a very difficult time lately in spots like this lately with JJ and QQ on low flops against unknown players, so any insight on this hand and others like it are much appreciated.
