possible radiator resrtiction
clean rad & cond at the car wash see if that wont help
check your fluids it is probably low on antifreeze and if it still does it change your thermostat that should fix the problem
The cooling system is probably getting old ... but to leave a car idling for 15 min is not a good practice for the car or for your gas milage.

Hey Tadd==I could tell you more if you stated what kind of car it was. Check the fan clutch or electric fan to make sure it is working properly. This should do it. GoodluckJoe
