Replace your ignition switch.

Suspect wiring problem inside the steering column.
There is intermittent contact failure when the steering wheel is moved.
Good luck in finding that.

I am going to go out on a limb here so bear with Me ,I will bet Your truck has a bad steering pressure switch only allowing the truck to run when pressure is applied to the steering .
