Hello, it sounds like you may have a faulty coolant temp sensor, if the car thinks it is cold it will keep adding fuel and when it warms it will cause the car to die. either that or you could have a clogging converter , can you tell me if there is a check engine light on and if you have done any tests on the car? besides replacing parts?

ok, when it dies, how long do you have to wait before it will start again?

Sometimes 20 minutes but something keep making it kills. Something stopping the water from flowing. I changed everything dealing with the water but its still something.

ok so what you need to do to give us a good path to go on, is when the car dies spray some starter fluid in the intake and see if it starts. if it does we know we are losing fuel, if it does not then we know we are losing spark.
