2000 Jeep Grand Cherokee engine shuts off

When engine coolant temp is cold or below normal the engine starts immediately without problems. When you drive away and engine coolant temp reaches 210 degrees after about 10 minutes the engine shuts off and will not start again for approximately 15 to 20 minutes. It continues this cycle indefinitely.

A faulty crankshaft position sensor will cause an engine to shut off when the engine/sensor gets hot.
