Jeep engine stops when it warms up

My 92 YJ has started cutting off after it gets warmed up. It will start fine and then start running rough and shut off once it warms up. Sometimes we can roll start it but it will not crank start. If we sit for an hour or so it will then crank start and shut off again once it warms up. We changed the Crank positioning sensor but thta did not help. Does anyone know what this could be?

just a guess but your coil could be overheating.
