Don't know how the ignition system on a Mustang compares, but for what it's worth I had an Olds 88 act like that a few years ago, and it turned out to be the ignition module.
It was fine while you were driving, but when it sat for a few minutes, or idled for a few minutes, engine heat would rise and the module would cut out. After it cooled off, it would work again. I proved it at the time by holding a handful of snow under the bottom of the module and cooling it off rapidly.

Like Goose said, I would bet on the ignition module. They had some problems with them in that era. It is mounted on the distributor and you will probably need a special wrench to change it without turning your distributor.

I have a '91 Bronco that quit while I was driving it. Turned out to be the ignition module mounted on the side of the distributor. If you decide to change it the distributor can be lifted a very short distance without disengaging the drive gear. Grind the outside circumferance of a 1/4 " socket to fit the hole in the module and it can be removed/replaced. Not sure if it is "1/4 due to a faulty memory so check before you grind the socket. I now carry the socket and spare module in the Bronco. 302 engine. Hope this helps. Pete

The first thing I would change is the ignition switch. Not the key part - the white milk jug plastic ignition switch under the column. It's the cheapest, most common and overlooked item on Ford's for a problem such as your's. A fuel rail sensor or a dirty fuel pump sock are other possibilities.
Module is usually the first go-to on a Ford. Kinda sounds like weak spark to me when it fired on ether...
Could also be weak voltage/bad connections feeding the module... and when cranking (voltage drop) it's not making a hot enough spark but when running it's making enough to keep you going.
