2000 Dakota Shuts off with no warning
i have a 2000 dakota 3.9 liter magnum 4x4. The truck starts up first turn but will all of a sudden just stop, no warning, there is no pattern to it, it could go for a few weeks or a few hours then all of a sudden shut off. I replaced the coil because when it does this it isnt getting spark, it started right up then same thing, just shut down and no spark again. went out this morning and it started right up again ran for a while then shut off again. The fuel pump is coming on. It just isnt getting spark when it shuts off. Any one have any ideas? Thanks in advance for your help.

Pull the codes (use the procedure listed here, and than the codes listed here), and tell us what comes up.
It might be your crankshaft position sensor.

Yes, the PCM is not recieving either a crankshaft or camshaft position sensor signal.
The following coming from the 2001 service manual, your truck should be very much similar.
Both sensors should be recieving 5 volts on the orange wire. The PCM provides a ground of these sensors on the black/light blue wire.
The crank sensor sends a signal back to the PCM on the gray/black wire, which appears to go to the PCM connector closest to the firewall (pin 8 of that connector). The cam sensor sends a signal back to the PCM on the tan/yellow wire, which also appears to go to the same PCM connector (pin 18 of that connector).
The 5 volt supply is sent via pin 17 of that same PCM connector, and the ground is provided via pin 4 of that same PCM connector.
The voltage reading from the crank sensor, I believe,should vary from very little voltage to close to 5 volts when the engine is turned over. The same may be true of the cam sensor.
