Router / Protocol Problem

Title: Router / Protocol Problem
I normally would not post to the group, but I am 100% stumped and have talked with peers with no luck.
I have (2) Cisco 7204 Routers running BGP with 3 peers and HSRP. I am not doing anything special with BGP, pretty much a default config that has not changed in years.
Recently with no changes to my network, I have been having problems connecting to certain websites and mail servers. I am always able to ping the sites and trace route without error. If I telnet to port 80 or port 25 it does not connect. If I login to my router and telnet sourcing my each of Internet Providers ports, I am able to get to the sites. I have talked with all the providers and none can find a problem. If I shut down one specific peer, everything works fine. So I keep thinking it was that peers problem some how. I have tested with just that peer up and I still can not connect. However, when talking with that peer, they are able to telnet from their network to the sites I can not reach. I don't know what else to check besides shutting down that peer. Which since it is under a 3 year contract, not an option. That isn't the real solution anyhow.
Can anyone shed some light on or off-list?
