My advice is that when the flop misses you, you can fold. If he is that aggressive you will get money off him when the flop does hit you. Your raise all in on the 2nd hand is horrible, he almost certainly will call with a king and any other hand you were probably ahead of anyway. You are not short stacked, wait for the right cards to come.

P.S. When an aggressive player who is the pre flop raiser checks a flop to you I'd be very suspicious.
