Mitsubishi Repair: Starting Problem, coolant temperature sensor, engine coolant temperature sensor

Question
I have a Mitsu Diamante 1997, and It won't start after I have made a couple of frequent quick stops. I changed the starter motor but no luck. Usually after I wait 10-15 mins the car starts back again. What would you think the problem here is if not the starter motor?

Answer
Flea,
This may be a problem with the engine coolant temperature  sensor or the cam angle sensor.  If either of those sensors are faulty, they can tend to malfunction when under high temperatures.  Once cool, they can send proper signals to the car's computer, and that will allow the computer to start again.  Have those sensor checked and replaced if necessary.
Good luck!
