SOURCE: car will start but cuts of at anytime have changed
try looking at the coil thats what they do work then suddenly stop working
SOURCE: pathfinder, cuts out when start out then why drive
Your car could cut out for many reasons. Here's the reason and solution to my own pathfinder cutting out:
One day, out of the blue, my Pathfinder engine cut out as I started to drive. It then cut out randomly. The way it was failing 'felt' electrical in nature, like a connection was going bad.
So, I'd start the car and quickly run out and start tapping on all things electrical. The MAF, or Mass-Airflow Sensor (not to be confused with MAP, the manifold air pressure), is located on the front airbox-airtube assembly and was a natural to tap on. The instant I tapped on it, the car died.
Did it again, and again, and again. The Mass Airflow Sensor was to blame.
I looked at the prices of these buggers, and they were in the $300-$800 range.
For that price, I'm going in!
I removed the MAF sensor by unscrewing the 4 screws.
I then managed to gently pry it open. What I found was a little control board encased in a jelly, presumably to isolate the board from the elements, and three little thin wires leading to the external connector. Without even having to break out the multimeter, I could tell that one of the wires had broken due to vibration fatigue or some other manufacturing defect. I recall I had to break all three wires to get the thing to open fully.
Soldering this was very difficult due to the presumably silicone jelly. It made the metal very resistant to bonding with solder. Without digging too much into the jelly, I exposed all wires and eventually, with scraping, fire, and flux, managed to get solder to stick decently to the various wires, adding my own jumper wires to make it easier to bridge the gap and close the case.
I needed to make this fix road-worthy, so I folded their wires around an insulating piece of clear plastic I cut from some plastic packaging material. The wires folded nicely into place and the case closed.
Several years later, the fix is holding strong.

This could be a number of things. Lets start with the wiring coming off the battery. The Nissan truck has a junction of wires at the battery, follow the red (positive) cable away from the battery. Check all the wire connections here looking for a loose connection or burnt looking wiring. If you have a test light or volt/ohm meter check voltage on the ign. coil positive side to ground looking for voltage. If the voltage is dropping out as the engine stops, that is the ign. circuit from the switch.
