Wont start after shutting off until it sits for awhile on 2003 Chevrolet Trailblazer

My trailblazer starts just fine at first. If I have to stop for gas, or walk into a store, it won't start when I get back in. I have to let it sit for at least 10-15 minutes before it starts again.

Really need to check for codes. Does it crank over and not start or does it just not do anything, not even crank over?
