The reason the data disappears is because it the query is timing out.
Click on the Server List Configuration in your Active Factory Web Trend.(Highlighted in Yellow)
In the Servers List Configuration at the bottom you will have "Timeout in seconds"
Connection from 5 to 10
Query from 120 to 240
Your queries should now succeeded.
