Check the ECT sensor and wiring. It would be best to do an OBDII enhanced scan to check for intermittent problems like crank sensors and such. Otherwise, you will be just guessing.
Oh a bad ECT will cause the PCM to think the engine is cold when itâ??s hot. This will cause a no start, poor idle and fast idle with a hot engine due to overspray or too rich a mixture.
