The truck listed above is a 1500. The ignition will turn on and lights and radio will come on when you turn the key and attempt to crank the vehicle all power shuts off and when stop attempting to crank it then they all illuminate again.

Hello,

It sounds like you might have a faulty ignition switch. Overtime the components inside the switch become worn and that can trigger very similar issues.

It can also happen due to a faulty lock cylinder.

Just so we cover the basics, have you tried to jump start it? Also, when you try to start it, does it make any noise? Any clicking?

I have attached diagrams below for your reference.

Please let me know if you have any questions.
Thank you.
