Some success today. I was able to get the S400 sync card to keep the output locked. However the content is still drifting. Here are the changes I made.
I noticed today that even though my WO preference was set to 60hz and I had manually set the displays to 60 hz (which I was able to verify on Decimator screen) when I took the servers online the decimators show that they are receiving 59.94 and if I go back to the AMD sync I see the output and no longer frame locked. The fix for this was to set the WO preference to 59.94, manually set the display to 59.94 and then sync all the display together. Now the sync still works when I take the systems online and they stay in sync on a reboot.
I also swapped put the production laptop for a server that is running the production laptop. Now everything is much closer, but their still a lot of drift. The majority of the time the servers are in sync but then it slips a few frames, catches up and then slip and catches up again.
