1990 Honda CRX Not running when warmed up

The car will start fine unless its too hot outside ( main relay problem ). I can get the car to start no problem but the issue im having is, the engine dies when it gets to normal operating temperature. I had an issue with the distributor rotor comming loose about 2 years ago but I put loctite on it. But just recently I looked at the rotor and it looked burnt and scratched so I put a new one into the distributor. The engine ran and then died in the middle of driving it. I noticed it was doing that when it heated up to operation temps. I dont know what else it could be causing this. I do know that the fuel pump works because I listen for it before I start my car. I listen for the Main Relay click before starting it, sometimes it wont if its hot inside the car. But Ive tried all I can think of.
