Help me play KK pre flop please

[noidea]

I play 2/4 nl 6 max
Last few days i have been haemorrhaging buy-ins in this situation.Its happened about 10 times.
I 2 bet with KK.Later position or blinds 3 bet between $50 - $60.I shove.They flip AA.
Am I supposed to go broke here every time?Should I 4 bet and fold to a shove?I know its player specific,but most people 3 bet 99, AJ in position,or from the blinds if they put you on a button raise.
I know this may seem like a retarded question but @ $1/2 , shoving pf with KK was very profitable.But ive never played in games where pre flop calling ranges are so narrow,so i am a bit stuck.

thanks
