Plus chaeck all vacume lines and make sure you have good spark. Electonic ignition will break down when they get hot. Than they are fine when they cool off

Could all so be the choke is not opening all the way when it is hot. Thats why it would run good cold and bad when hot

On 95 models where the top radiator hooks to engine there is a two wire temp sensor mounted close to the thermostat housing. the sensor could be going bad and will cause engine to run bad or not at all, and some times it will not set a code. Sensor,s are not that expensive.
