It could be the problem but it sounds more like a fuel or air problem. You can remove the module and have it checked at most parts stores. That is pretty simple, and would be an easy check. I had a bad module on my 83 2.8 that was similar. It would start but after a few minutes the engine would quit like you shut off the key. After several minutes it would start again, but not run too long. It wasn't missing or sputtering though, so that's why I am thinking more in the area of a fuel supply problem. Keep us posted.

Forgot to mention-It is a lot easier to pull the distributor to change the module, however you can do it on the engine if you don't wan't to mess with the timing. I use a felt tip pen (red works well) and make several index marks on everything so it goes back in the same way it came out. That way you don't need to find TDC on #1. Make sure you use the heat-sink "goop" if you remove the module. If you get a new one, it should come with a small tube of it. Looks kind of like vaseline, and is very important to keep the module from developing hot spots.

If you can pull any codes I would do that first. Mine showed up as a "Spout" (sparkout) failure. Then check the distributor cap to insure it's not cracked or has carbon tracking on it. I just replaced an ignition module on my '90 Taurus. We had it checked and it would check out good sometimes and then fail the next time. And it's important that you mark everything on the distributer's position carefully at several spots with that scriber before you remove it. Note the direction of the rotor as well. I had to buy a socket that fit those weird size little hex head nuts on the module. Before I replaced the module it had all the symtoms your's exhibited. It was a pain removing the distributor on the 3.0 liter and getting to that hold down bolt, but it was the only way I could get to that ignition module. And all the previous information was correct and don't forget that heatsink compound when you put on the new module. Good Luck!
