ALLData's information on trouble code 14 says that there is a short somewhere in that circuit, and not necessarily the igniter itself. It could be the igniter, a wiring problem, or the ECM itself. You should definitely trace the wiring there and see if there are any bare spots in the wiring. Personally, I would see about replacing the connector coming from the igniter, whether or not you see any issue from it.
It would not be a bad idea to actually check the sparks when it's acting up either. You can get a spark tester for roughly $15.00 at AutoZone. Here is the one I have:

Just take the plug wire off of the plug, and plug the tester in between the plug and wire. Then have someone crank it and observe the sparks. They should be bright. Very bright. And consistent. Check all cylinders.
Finally, have you checked the fuel pressure when it is shutting off? Personally, that is what I would suspect. Sometimes fuel pumps will lose pressure when they get good and hot, causing the car shut off. You can borrow a fuel pressure gauge from the local auto parts shops (AutoZone, Advance Auto, and O'reilly). Here is a how-to guide:
