FUEL SHUTOFF?

3 ltr Ford Ranger
Every few days I have a sputtering engine shutdown. When trying to restart there's no sound of the fuel pump whirring. After about 20 minutes the car will start ok and run fine for a few days. Have replaced the fuel filter, fuel pump, fuel relay, and PCM relay. After driving 20 minutes or so I notice the two relays are hot to the touch. Have you an idea of what the problem might be? Thanks

Do you

Suspect fuel pump may have poor ground causing high amp draw

Also check for corrosion at the fuel-pump cutoff inertia switch. It is located on the passenger side floor, at the front of the carpeting/floor mat near the firewall. It has a red reset switch on it. The connectors on these switches, due to their location, are prone to corrosion.
