Question about 1985 Toyota 4Runner
What is the most likely cause? Relay at fuse panel, Relay behind battery or pump itself?
Check injector(s) first. use mechanic's stethoscope or can use the tip of long screwdriver and must hear the injector(s) clicking(if the car doest not start,have someone crank the engine). if has no sound, injector not working. and check also coil resistance.

SOURCE: EFI underhood relay
I would replace the relay that gets hot, and make VERY SURE that the relay pins fit real tight in the female receivers for the relay. A *** slight *** amount of clearance at the connection will arc & def heat up the relay. Once relays get really, really hot, it, at times, they may no longer be reliable.

I need to get a clear mental picture of what exactly is happening.
With this said, you stated that the car "runs fine" until warmed up.
Q: When you start the car when cold it idles fine?
Q: If you allow the car to idle until "fully" warmed does the car stall?
Q: As the car begins to warm up, Does the RPM fluctuate abnormally?
Q: Does the car Only stall when you press on the gas pedal or does it stall just sitting and idling in addition to pressing the gas pedal?
Q: If you can drive it while cold does the car stall during acceleration when warm or only at Stop Signs / Lights?
Q: If you wait 20min or so, can you start the car again?
Q: How many miles are on the car?
