The most probable cause for this is a an intermittent problem with the Starter solenoid and/or starter.

When the car does not respond to turning the ignition key on can you hear a click from under the hood?

If you can that is the starter solenoid trying to turn on the starter motor. I would say the starter needs to be replaced.

If you cannot hear anything, then the solenoid ( which is just a relay) is probably bad.

I just replaced my startere on my F150, starter & solenoid come as a unit.... cost about $125.

Hopes this helps good luck Loringh

First, obviously, put gas back in the tank.

Check the fuel pump fuse, (20 amp yellow fuse in the lower left corner of the group). If that is not blown, turn the key on and pound hard on the bottom of the fuel tank. The fuel lubricates the fuel pump, once it runs dry, the pump can lock up. Once the pump is immersed in fuel again, a sharp jolt will unstick it and let it pump up to pressure again. If it locks up for too long, the pump will burn out and need replaced.

We found this out by accident, got mad and pounded on the bottom of the tank and the pump jumped to life.
