AnswerHi,
You did not make reference to the year, make model or year so I am somewhat at a loss. It sounds like possibly you have a loose connection on a bulkhead connector at the firewall.
Power is supplied from the engine area to the passenger compartment at this connector.
You could also have a bad connection at the electrical ignition switch. Your description leads me to believe it is a connector though.
