The most likely reason is a disruption in the network, possibly involving
firewalls.

You could check in the SQL Server errorlog to see if there are any
stack dumps that can be correlated with these disconnections. In such
case it could be a bug in SQL Server. But network problems are far more
likely.

Any particular reason that you use named pipes rather than TCP/IP?
