Its a shared inside interface for both outside interfaces, that is what is throwing me for a loop. One idea I have it to create a second physical connection on the inside, use the ASA just as two firewalls in one and move the routing back to the core switch (4510).
Single firewall with links from one internal private network to two external private networks.
End result seems to be that the ASA cannot do the VRF routing that is needed for this application. I moved the routing point back to the 4510 core and just used the ASA as two independent NAT/Firewalls and it is working now.
