It could be anything from a bad chip in the key to a sensor in the steering column. I hate to say this, but the only place that will have the proper test equipment to diagnose the problem is a dealer.
As far as the letting it sit for 10 minutes with the key in the run position, that is a means of bypassing the system.
Let me know if you have other questions.
