AWS VPC Connection dropping

Using this guide, http://www.seattleit.net/blog/pfsense-ipsec-vpn-gateway-amazon-vpc-bgp-routing/ we were able to get a PFSense IPsec tunnel to connect to AWS. We can ping bi-directionally.
However, our tunnel connection drops constantly. We’ve been working with the Amazon techs and, while they don’t have experience with pfsense, they did look at our configuration and they said everything looks fine. The fundamental issue seems to be that they are closing the connection because, from their network’s point of view, there is no interesting traffic. Their recommendation to have our networking keep a running ping to one of our EC2 instance has no effect.
Furthermore, we have a secondary gateway configured to fail over to and when it tries we get a lot of this: unknown Informational exchange received, and then this: phase2 negotiation failed due to time up waiting for phase1.
I have quadruple checked the only difference between the two gateways for all phases is the ip address and the pre shared keys.
Thanks in Advance!
