Ignition Switch?

When my car is cold, starts first turn of the key. But when hot nothing happens. I have to get out and jump the terminals on my starter and starts first try. So I know its not a voltage problem. ignition switch maybe?

Hi there,
maybe heat-soaked starter solenoid? Any click when you turn the key? Very common problem on big-block v8s, possibly on v6s as well.
