Distributor

Replace it to see if the problem is solved. There is nothing you can test inside it. Older cars often had a simple two-wire pickup coil where you could measure if it had a broken wire. Normal resistance was around 500 to 850 ohms. Almost everything today uses a three-wire "crankshaft position sensor" and a three-wire "camshaft position sensor". The cam sensor can be in the distributor. If that signal drops out while driving, on a car as new as yours the engine might continue running until you turn it off, but it usually will not restart. By that time a diagnostic fault code will be set in the Engine Computer related to that circuit.
