It sounds more like you have a loose connection. Check the ground wire and power wire. Follow the wires from the connector and check that they are not loose. If they go to a splice check both sides of splice. Follow the ground and make sure it is tight and connected to metal.Check power wire at fuse holder and make sure it is secure. Also make sure the connector is properly connected to the rear of your unit.
