Have you checked the easy stuff like the battery? Could the ignition switch is bad? What year and model?

How did the Battery check out?

Voltage without load?
Voltage with applied test load?

We're coming back to the battery as it would be typical for a dead or dying battery to have this symptom.
I've seen this particular behavior before in cold weather. While when warm the battery was just able to start when out in the cold the battery looses part of it's performance. Switching the truck on yielded nothing at first. The load applied was sufficient to warm the battery to come slightly to life but it failed cranking as yours did.

That's why it would be important to know the voltages without and with test-load.

Another small possibility could be bad battery cables??? Corrosion on the terminals connecting to the battery??? Just a thought
