I'm sure John knows this stuff better than I. But more basic, a coil boosts the voltage of the spark that goes across your spark plug to thousands of volts from the 12v that is in your system. I did not realize the 6cyl has 6 coils, one for each cyl. The Direct Ignition (DI) that I am used to on the 4cyl is also basically one coil per cyl. There is much more to it, but the coil is the source of your big spark. Or not.
If the DI or individual coils fail, the car sputters or stops. Same as if your spark plugs were bad. Or on older style cars, the plug wires or distributor in the ignition system. So it sounds like the high voltage is not getting to your plugs.
