My 97 camry keeps shuting off while driving it has a new battery new alternator new wires new gas pump new radiator new timing belt new starter new crank sensor new fuel filter and new ecm and it still keeps shuting off I don't know what else to change I put it on the computer like 6 times and nothing comes up but I noticed that when I'm driving the check engine turns on and that's when it shuts off

Put the plug to the MAP sensor when it happens again. (Guess)

What are the symptoms when you try to re-start it?
Any relation to operating temperature? Like never does it when the engine is cold.

Replace the coil.

If you say the timing belt was done, then look for the crank sensor wire leading down the upper timing cover.
Is that harness secured to the timing cover? I've seen countless times sloppy work and the wire rubs on the alt belt and causes intermittent open to the crank sensor.
What's the mileage? Some high mileage cars may require a new ECM.

My Toyota vista keep shutting down when I driving and I have change a number of things and my mechanic seem not to know what is wrong/
