I have had similar problems, except for cylinder 5. Replaced the spark plugs, worked for a while. Broke again, replaced the coil packs, worked for a few days. Broke again. Just found out there is a crack in cylinder 5, coolant has filled that cylinder, the engine is a loss. That will be $10,700 please. Ugh. Done. Taking the loss and getting the **** outta this thing.

How many miles on your vehicle? Any powertrain warranty left?

I've just had the same issues. Check engine light on, P0306 code. Had it cleared because the car ran fine, 2 days later won't start and engine seized.

Have you been losing coolant? Sounds like your cylinder 6 has been filled with coolant leaking from the head gasket and cause a hydro-lock which would probably have fried your starter. Let us know what you find out about the issue.
