Before you go changing out the starter check for a burnt out fusible link going to the starter it will look like a wire but acts as a fuse and they burn in two just like a fuse. The symptoms you just describe are those of a burnt fusible link.

On the firewall is the starter motor relay. There are 2 large battery sized cables to it, and 1 smaller ( 16 AWG ) wire that is orange or orange with a stripe ( forget the color, want to say white or tan ).
When you turn the key to the start position, check the smaller gauge wire for +12 V. The case should be ground. If you do not get +12 on the orange wire, try starting the truck in neutral ( apply the parking brake, chock the wheel, etc normal safety precautions ). Test for +12 V at the small wire. This is the output of the DTR ( Digital Transmission Range ) sensor or in common terms the Neutral switch. The start position on the ign switch runs through the DTR to the starter motor relay coil.
If you have a stick, the DTR is replaced by the Clutch Pedal Position Switch ( clutch must be pushed in to start ).
If you have power to this ( at the times the truck won't start ) next is to check the both battery cable ends to see if they are corroded and making intermittent contact ( not probable but possible ).

Have you checked for 12 volts coming in going out of the the starter solenoid switch that is mounted passenger side fenderwell.
Testimonial: "No but that is logical; thanks! You can start the truck by 'jumping out' that same solenoid."
