Network Timeout

I have two wordpress blogs running on a 1&1 server. For the past two weeks, I have been able to log in as admin on either site and work on it. But after a random period of time or commands, I begin getting a Network Timeout error.

It also resets itself each night, so I have a short while to work on it each morning.

Any clues or suggestions?
