(nothing major)

All in all the motor runs great, but sometimes after driving it around for a while, it wont start up after I shut it off.

I'll let it sit for a while, crank it while giving it gas and then she starts up.

The car will idle will low then kill itself when this happens.

This happens very rarely, but nevertheless, I'm a bit worried. Any help will be appreciated.
