Intermittent shutting off while driving

My van starts up runs good may run for twenty minutes may run for three hours and all of a sudden it will shut off going down the road at highway speeds. You pull over sometimes it will start right back up sometimes it takes a minute to start. I still got tachometer when the car quit so I can still see the rpm's and I hear just a little ding right before it shuts off. If anybody could help me with this I will gladly appreciate it. I have change the cam sensor, crank sensor, it has a brand new fuel pump, fuel filter, plugs, wires, and coil pack. I checked the the cluster is good. I checked all the wires coming from the injector wires wires to the crank sensor to the cam sensors wires coming from the the PCM and they all appear to look okay.
