Since the steering wheel becomes stiff sometimes when the steering wheel rotates then the most likely cause of the problem is a faulty power steering pump this pump is occasionally failing. When the pump stop pumping power steering fluid for a moment there will be no hydraulic pressure causing the steering wheel becomes stiff for a moment.
