Battery is good. No crank after driving around.
This one is a confusing one. My battery is brand new. Alternator is new and has a voltage of +- 14 volts in idle. When the Camaro is "cold", she cranks fine. But when after I turn off the IROC after a good 1/2 hour of driving, she wont crank at all. Voltage is normal. No click or anything. Then after a couple hours of cooling down, she will turn over and start? What may be the issue here?

I used to have a similar issue. Mine was over heated starter with my timing being too far advanced.
