Why 2002 toyota Corolla won't start after a hour or so continous driving.

Well, I'd have to ask if you mean; it does crank (spin the engine) when I turn the key and not start, or nothing happens when you turn the key? The answer leads to two different areas, the first being fuel or spark problems (like distributor), the second being battery or starter or even ignition switch. I have my guesses but would like more information. Dana Meyer Dana Meyer Auto Care
