It didn't idle for an hour or else it wouldn't have "cut out." I assumed
she ran out of gas, and with the lights, stereo, and whatever on the
battery could easily have gone flat in that time. Also, in-tank fuel
pumps do not like being run with an empty tank since they rely on the
fuel for cooling.
However, if there's fuel left the pump should be alright, but so should
the rest of the car.
In addition to the previous posters:
By does not start do you mean that the engine does not spin when you
try to start it...if so:
Did it overheat? Run out of oil? If so it is toast.
If it does...I'd really look into the gas situation as mentioned
If the alternator could not keep a charge on the battery at idle, you ought
to have the alternator checked out. You could find youself in the same
situation if you are caught in a bad traffic tie-up. However, most modern
charging systems ought to be able to cope even at idle.
