My saturn starts well when cold. Once I drive for 15 mins and turn it off, it won't start again right away. I have to wait for it to cool down and start again. What could be the problem?

Possible electrical issue or a vapor lock problem in the fuel system. When it doesn't start, check fuel pressure and ignition spark to the plugs, and make sure the injectors are operating properly. Also, check the engine module for diagnostic trouble codes.

I replaced the battery when this problem was occurring during the cold months and have had no problem since.
