have you tried pushing in on the ignition as you turn it.you may have to push hard.that should be just a new ignition,otherwise it could be in the ignition circuit. I also had this problem and the dealership could not fix it. so I replace the Ignition switch and that fixed the problem.
Defective ignition switch.
