1996 Geo Tracker Ignition Failure

CAR DIES INTERMITANTLY, WHEN IGNITION CUTS OFF
REPLACED CRANK POSITION SENSOR
CHANGED TO A REBUILT DISTRIBUTOR
REMOVED STUFFED CATALITIC CONVERTOR
TO NO AVAIL
MUST BE 1 OF THE 4 SENSORS (OXYGEN, CAM, CRANK or THROTLE SENSORS)
HOW DO I KNOW WHICH OF THE ABOVE 4 SENSORS IS BAD???
I'M IN MEXICO, WITH NO CHEVY SERVICE FOR THIS CAR AVAILABLE
:nono:

After your car stops running, will it start again after sitting for a while? If so, sounds like an in line fuel filter needs to be changed. Hope you find a solution to your problem soon mi amigo.
