Car died while driving, ignition help!

If you're getting sparks ( not just 1 spark but sparks ) from the coil wire while turning the engine over the ignition is working ( at least when in start ). The fault would have to be in the cap, rotor button, plug wires. If you het only 1 spark from the coil each time the key returns from start to run, the ballast resistor or ignition switch is the problem.
