I'd be willing to say it's the main relay, very common with these.

What do you mean by "quit driving"?
What exactly does it do? Motor stop running but you still have power to the electronics?

if its starting and driving then dying while on the road all the sudden then it isnt fuel related

If it completely died while driving and you can't start it up but you have power, it could be a bad coil in the distributor. I had this happen to me driving on the highway. Motor shut down, still had electrical power but wouldn't start or crank again. Replaced the distributor and it was good to go.

If you can still crank the motor then it may be fuel related.

this a very vague question so here is a broad answer.
an engine requires 3 main things to run: fuel, ignition, air

could be no fuel
could be no spark
could be no air
