Problem with controls

susiepops

On waking up after a nights sleep our water and lights were not working.  On looking at  control panel the main switch was still on but the individual switches on the control panel had switched off. We put them on again and lo and behold OK.  Any ideas? 
The M/H is a 2009 Autocruise Starspirit with a control panel nr door which has all the switches for lights etc and measurement of waste and clean water and voltage reading.Any help would be appreciated.
