Start by having the diagnostic fault code(s) read. Many auto parts stores will do that for you for free. Those codes will indicate the circuit or system that needs further diagnosis.

Check the fresh air tube between the throttle body and mass air flow sensor for crack or leaks. If any air sneaks in there that the mass air flow sensor doesn't know about, the Engine Computer won't command enough fuel to go with that air, and stalling can result.

Any mechanic can check for codes but they can be somewhat primitive on '95 and older models.

To check the fresh air tube, look at it visually for signs of dry-rotting, cracking, loose hose clamps, etc. As I recall, it's along the firewall on the passenger side, under the hood, at the rear of the engine. It should be black, about three inches in diameter. It will come out of the box where the air filter is in. One fellow found a small crack on the back of his where it had been rubbing up and down on the firewall when the engine rocked back and forth. The temporary fix was to wrap electrical tape around the tube to cover the leak.
