Shut off while driving and won't start
 

Hoping someone can help. My Durango has been running fine. Got in it yesterday morning, drove 1/8 of a mile up the road and it just shut off. It turns over but won't start up. It's getting fuel, it seems to be firing. Ran diagnostics but not codes. We replaced: cam sensor, crank sensor, rotor button and distributor cap. Appreciate any suggestions.

What's happening when you turn it over? Does it start at all, or does it just keep trying to turn over?
