Starter or starter cylinoid would be were I would start what does it do when you try and start it

I have an 07 colorado and had this very same problem. Ocassionally i would hop in the truck and stick my key in...it would turn over but not crank. I read numerous threads that is was my crankshaft position sensor....like you i would wait ten minute and it would crank right up. After i replaced the sensor, 2 weeks later it did it again. Read more threads...got a brand new key and took off all of my keys to reduce weight on the ignition cylinder. 2 weeks later it did it again. Finally I figured out that all of those threads were wrong. My passlock light was flashing during those 10 minutes of waiting for one reason!!! My positive battery cable had corrosion on it. Even a little corrosion on your terminal will trick the passlock sensor into thinking the truck is being hacked and will not crank. Take it from me, clean the **** out of your terminal wire the proper wire brush and neutralizer, then coat the terminal and cable connection with a pile of either bearing grease or diode (red) grease to help prevent future corrosion. 4 months later i still havent had the problem come back, and I had it happen over 6 times in two months. Try it and see.

Shift solenoids need to be looked into.

Someone will need to figure out if you are lacking spark to the plugs or fuel to the injectors when it won't start.

Common on Chevy products, known as key in circuit failure, what it means even if you take out the key the ignition remains on and drains the battery

check and see if you have 12 volts at light socket board, possible blown fuse or backup lamp switch bad

Have your charging system tested and include the Battery. Go to Autozone.com ,register your vehicle for free, get free wiring diagrams and Fusebox layouts. Have a starter draw test done.Check the relays for the fuelpump, ignition, and PCM. Sometimes the horn relay can be the same part number and be interchanged.What you are describing can be many things. You have more compression in a hot engine, you have different timing in a hot engine because vehicles run so lean today. The O2 sensors may be keeping the engine too lean to restart after a warmup. Relays can overload when hot and kick out the connections. Your fuelpump can be failing.You did not indicate how far you drive when this happens. If you are driving 10 miles a weak battery will not recharge, but a 100 mile trip gives it more opportunity. The starter draw test will tell if the starter is bad. The starter may cool down overnight, but frequent restarts may heat the starter with it failing.
