Going to take some detective work with a meter and a schematic. Before doing anything else, I would clean and tighten all of the major electrical connections - battery terminals, alternator terminal, starter connections. I would start with checking if you are getting voltage to the starter when you turn the key. Then you will need to backtrack from there working your way up the circuit. If the starter terminal is accessible enough to get a jumper cable on, you could try jumping direct to that to see if you get cranking. Have to be careful doing that. Problem with the ignition switch would certainly be a possibility. Starter relay perhaps a little less likely since it should have had no effect on your orignal problem of it dieing while driving. Jumpering directly to the starter, if possible, would eliminate anything circuit related - relays, wiring, etc - in the starter circuit.

And a late thought; you're sure the battery is up to full charge and able to take a cranking load? Having the other lights, etc working is not necessarily a good indication of battery condition.

Check the battery cables
Make sure they are tight to the battery (though I have had these exact symptoms-lights work but not enough juice to start engine- on an overtightened cable to post also)
And make sure there is no corrosion...especially hidden under the cable's plastic coating
And check for loose ground wires also

In addition to checking the battery cables and connections I would also check the fusible links by the starter. There are either three or four of them, they protect the wire in the event of a short circuit. A quick tug on each one is the quickest way to check them, the bad one will stretch or break.
