Chevrolet Repair: Car, crank sensor, chevy impala

Question
Why after an hour of driving my 2000 Chevy Impala want start until it cool down after 1-1 1/2 hours?

Answer
HI DARRYL, WITHOUT A DIAGNOSTIC TEST WITH A SCAN TOOL FOR DATA,THIS IS JUST A GUESS. CRANK SENSOR IS GOING BAD MAYBE..GETS HOT, WONT START. VERY COMMON. ALSO I HAVE SEEN IGNITION CONTROL MODULES DO THIS AS WELL..BUT WOULD HAVE THIS CHECKED BEFORE REPLACING IT..DONT LIKE TO GUESS.GOOD LUCK,,TOM
