The window has nothing to do with it and I never heard of a kill switch. THere is an Auto Shut Down (ASD) for the engine, but that won't kill all of the electrical system.
Have you checked to make sure the battery terminals and grounds to the engine block are clean and tight? I realize that may sound elementry to you, but many times that causes the problem. Also, does the battery have a good charge producing 12+ volts?
