The engine shut down while driving, any ideas?

is it an ignition [loss of spark] =fuel issue [fuel pump--filter] scan vehicle for codes active or pending ---usually fuel pump--cat converter--short in wiring dont pull a code --

The fuel pump relay is a small unit covered in a plastic case, which has several sprockets on one side that are clipped onto the ignition system. The fuel pump relay is what turns on the fuel pump when you start your car and powers it down when you shut off the ignition.

The engine control module (ECM) uses the fuel pump relay to control when the fuel pump is on. The fuel pump relay supplies electricity to power up and power down the fuel pump.

It's located in different places on different cars. It could be under the hood, on the firewall, on one of the fender covers or near the steering column, to name a few locations. As for a Nissan Terra (Nissan Terra ?????), it is often found in the fuse box located in the engine bay.

When you turn the key in the ignition forward to crank the car, the "start cycle" begins and fuel pump relay is engaged long enough to turn on the fuel pump. It shuts off again when the engine is running. Once the engine is running, the fuel pump relay shuts off, and the current for the fuel pump is supplied by the oil pressure sending unit. The other time the fuel pump relay is engaged is when you shut off the ignition. It engages long enough to shut off your fuel pump.

most commonly found problem relates to an electronic component heating up and shutting down. Have you checked to confirm there is fuel pressure when the vehicle shuts off. Is the check engine light on. Have you checked codes ? I suggest hooking up a fuel pressure gauge and letting vehicle run till it shuts off while monitoring the fuel pressure. If you loose fuel pressure, next step is to confirm there power going to the pump, if there is power going to the pump with no fuel pressure replace pump. Another suggestion would be to check for spark when vehicle stops running to eliminate an ignition problem. good luck

When the engine stalls;
Test for spark (ignition)
Test for fuel pressure & check fuel pump volume

The only way to know for sure is to hook a gauge to the rail and check the fuel pressure when it won't start.
Sitting for a few minutes and restarting is normally a sign of a relay or coil cooling off.
There should be a EEC relay that powers the dist module and ECM.
I know you said you have spark, but it could be something else
related.
Also, if you have spark at the right time and no fuel pressure, you should be able to use starting fluid to substitute.
I don't suppose you have dual tanks and the switching valve is the problem ?

Fuel pumps don't have anything to do with spark. Have the codes read. My guess you lost the crank sensor, ignition module, or coil. Check your fuses also.

do you have ignition fire? does the check engine/service engine soon light come on when when you turn the key on? can a scan tool communicate with the ECM? there are several things to check if you have no power to the fuel pump because the fuel pump relay is controlled by the ECM.

I would replace the crankshaft ignition pickup (Crank position sensor)

The power supplied to the fuel pump, ignition coil, fuel injectors, and parts of the power module is controlled by the logic module through the Automatic Shutdown Relay (ASD); the idea is to shut off fuel pressure and the ignition systems when the key is turned off to prevent fires, dieseling, and other problems.

The ASD relay is closed (allowing power to flow through it) when the ignition is first turned on. If the signal from the ignition reference is lost while the engine is running, or if the turbo boost pressure reaches and exceeds the over boost cut-off point, the logic module cuts power to the ASD, which in turn removes power from the fuel pump, ignition coil, injectors and those parts of the power module. This causes the engine to shut down.

Failure of the automatic shutdown relay is often shown as inexplicable stalling or refusal to start.

sounds like a fuel filter problem, when the engine shuts down,the blockage settles, then when driving, the fuel pump draws the blockage back.......check fuel filters
