Yes, sorry I should have mentioned that.  I have the private key.  The ssh debug output suggests I'm not even getting to the stage where I would submit an authentication key.

$ ssh -vvvvv ec2-user at 52.4.7.x
OpenSSH_6.2p2, OSSLShim 0.9.8r 8 Dec 2011
debug1: Reading configuration data /Users/rhornsby/.ssh/config
debug1: Reading configuration data /etc/ssh_config
debug1: /etc/ssh_config line 20: Applying options for *
debug1: /etc/ssh_config line 102: Applying options for *
debug2: ssh_connect: needpriv 0
debug1: Connecting to 52.4.7.x [52.4.7.x] port 22.
debug1: connect to address 52.4.7.x port 22: Operation timed out
ssh: connect to host 52.4.7.250 port 22: Operation timed out

Adding "-i /path/to/private_key" to the ssh command makes no difference at this point.
