Vehicle dies suddenly while driving and then starts up immediately. It does not sputter or miss out. If it does not start immediately on its own, it will crank and crank before it catches. We have recently replaced the batteries and the camshaft sensor based on the check engine recommendations.

Do below to determine whether it's fuel or spark problem.

Cranks but no start condition:

Fuel and Spark:
Get a helper disconnect a sparkplug wire or 2 and ground it to the engine at least 3/16 away from ground -have helper crank engine over-do you have a snapping blue spark? If so-you have a fuel related problem, check the fuel pressure to rule out the fuel filter/fuel pump/pressure regulator and listen to the injector/s are they pulsing or hook up a noid light. No snapping blue spark continue to troubleshoot the ignition system-power input to the coil/coil packs,coil's resistances,distributor pick-up coil, ignition control module, cam and crank sensors and computer Note: If it doesn't apply disregard it.
