Faulty Fuel Pump Shut-Off Switch?

My '04 Ranger Edge (I'm the original owner) has 80K miles on it. It wouldn't start after I parked it at a store after about an hour of driving. It was the fuel pump shut-off switch, and I just reset it and everything was fine. I had not jolted the truck, though, so I don't know why it tripped. It happened again last weekend, same scenario (hour's drive, just parked, no jolting), except that the truck wouldn't start for about 20 minutes, after I reset the switch. Is the probable issue a faulty shut-off switch? I tested the fuel pump relay and it checks out okay.
I'm hoping there's a Ford mechanic out there with some experience with this problem.

Why does it seem only Fords have this switch ?

Does it seem that the connector to the switch is OK ? Can you squire some electrical contact cleaner inside the switch .

I know what I would do . But I probably do not need to say it on open forum .

God bless

Most likely the pump is about worn out and is drawing excessive current overheating the collision switch.

I have replaced a few collision switches because of this.
Use a amp meter to test fuel pump draw.
No, I don't remember the normal amp draw.
Good place to start would be replacing pump and switch.
