Im not the best mechanic here by all means. But if he applies power to the soleniod and it cranks right up after the motors hot, then the soleniod is still working. I may be missing something also. But I have seen ignition switchs go bad. I beleive the ignition switch carrys an electrical load threw it when the key is on. So it could be heating up and loosing contact. But bypassing the switch under the dash would be a quick test. He already ruled out the soleniod by jumping it with a hot wire while it was hot.
