I am just reporting back that it was fuse #13. What we found was that the fuse looked fine and tested fine on the front, but when looking at the back, one end was broken and not connected to the end. I find it hard to believe that it would keep running without the fuse, but then would not restart after shutting off. I verified that this is the case today. When I first started testing I am pretty sure there was no power to the left side of the fuse and that is why I replaced the ignition switch. With the new switch I had power to the left side of the fuse, but not the right. These fuses don't hold up very well to vibration caused by driving gravel roads.

I was very gentle when pulling the plug from the Chrysler control box, so may not have caused any damage.

It doesn't idle very smoothly, but is no longer dying. I'm having trouble convincing myself to do any more work. She gets us to town and back getting about 20mpg, so I think we'll just drive her.
