My 04 Ram has an intermittent problem starting. It started out of the blue in October. I took it to a garage to replace parking brake cables and got a call from the tech saying it will not crank. It eventually started. When I picked it up I had to hit the key several times. Then I didn't have a problem for 2 months. Now it wont start again. I suspected the clutch interlock switch. I bypassed it and still no crank. Is there a common problem with these? Ignition switch possibly?

Thanks. Lew
