Why does 1997 Infiniti Qx4 shut off while driving?

A 1997 Infiniti QX4 may shut off while driving due to several potential issues, including a failing fuel pump, clogged fuel filter, or ignition system problems, such as a faulty ignition coil or spark plugs. Electrical issues, such as a weak battery or bad alternator, can also cause the engine to stall.
