if a fuel pump relay is bad the fuel pump will not even come on. It could cause the vehicle to stall but I would look elsewhere first. Have a mechanic check the fuel pressure. You can check the relay by applying 12 volts to the coil side of the relay and that will cause the contacts to close and you can check voltage at the contact side of the relay. If your fuel pressure is fine I would check the ignition system. Are you getting fire to all your spark plugs. Is the check engine light on? The ignition control module can cause a stall when it get hot. More troubleshooting is needed to pin point the problem..
1997 are prone to having a bad ignition switch. It can cause stalling, hard shifting, crazy dashlights, hard start, no start,
