The connection to your ESS is assumably managed by your filemaker server. Thus you need to setup the timeout time in the settings of the ODBC DSN on your server.
As you noted above: "MSSQL Native Client drivers 10.0"
find the settings for this, and there should be some sort of timeout setting in there. The timeout for ESS is unaffected by Filemaker GO itself (as noted, within two hours it works), it is assumably affected by a "countdown after connection" setting in the MSSQL connection settings.
Unfortunately I'm not familiar with the MSSQL as I'm normally connecting to MySQL data. Hopefully this gets you started though.
