Possible weak spark from ignition coil or low fuel pressure due to weak pump. Try spraying carb clean into intake throttle body when problem is present. If vehicle will start and run with a little spray then fuel pump is failing.

i had the same problem, and it turned out the coil pack was moulding inside wich stopped the spark all together, i ended up changing my coil pack and putting on new wires because the ends connected to the coil were very corroded and that cures the not running part just fine

Not the igniton switch, its the ingition cylinder and or the housing. The switch is not part of what you are really turning. It's connected to it via gears. The common problem is the key gets worn out and the tumblers wear also. Eventualy they do not line up right and will not make the "bar" drop in the cylinder to allow it to turn from the off positon. If you have the title in your name and the key has never been rekeyed or the code has been changed you can go down to a dealership with all of the info for the truck and they can cut you a key from the vin number. You can try that first before you put a cylinder and housing in it.

Testimonial: "I really appreciate this info it makes sense and hopefully this solves the problem. it gets really annoying not being able to start the truci"

Sounds like a bad ignition coil. Check for spark right after it quits Coils can and do quit working after they get hot. Also check magnetic pick up coil in distributor. After reaching operating temp computer will move the coil and a broke corroded wire loses connection. Then when engine back to cold wire is back in contact and working. Hope this helped.
