My 99 integra shuts off when it gets hot but starts when it's cold. Need help

 

Check and Test the Ignition coil inside the distributor or try a working one,
Check and test the ICM inside the distributor or try a working one,
Check and Test the ECT sensor (Engine coolant temp sensor) located on the side of the cylinder head.

Should be either one of those sensors that's bad, ill lean toward the ignition coil or ICM in the distributor, both are very easy to replace.

I remember your last post you stated when you replaced the ECT the problem went away, 90 % chance its still the ECT but not the sensor~, pull out the plug and inspect the wires going into the plug, pull out the small plastic piece inside and inspect the wires and make sure they are pushed in all the way, MY ECT went bad but I found out it was just the wires that got pulled from the plug and it wasn't making full contact with the sensor prongs.
