My power windows sometimes stop working for a few seconds, and if I try pressing the controls they don't respond. However if I wait for 5-10 seconds and try again, it works. This seems to be a problem with *all* the windows in the car, and happens with all the controls including driver side master controls for all windows. Is there a common part that could be at fault?

First you need to use test light and check master switch . If wiring is OK then suspect faulty master switch.
