I have to ask, how long since a tune-up?
Are there any applicable trouble codes?
I saw what you replaced, didn't see any testing? With intermittent issues, have to do testing when problem is ongoing. When problem is ongoing, if it cranks good but won't start, have a helper crank it while you check for spark at the spark plugs. If spark everywhere, use a gage and check proper fuel pressure. Also check fuel injector pulse.

Car shuts down while driving

It is very likely the part that is giving you the problem is a Crankshaft Position Sensor, they go open circuit when they get hot, then after it cools it becomes a good circuit again, this is very frustrating, had the same issue with my Buick a few years ago, replaced the coils and the ignition module at a cost of hundreds, DID NOT CHANGE A THING, the crank sensor fixed the problem and was $30.00 from Buick.
