The car sarts and runs fine. after 10 or so minutes it dies. restart it dies in 15 seconds. restart it and runs 10 or so minutes and dies. repeat procedure over and over agian. it does not matter if it is idleing or running at 1800 rpm it just dies. We have put in a new fuel filter, plugs replaced coils with known good ones. changed computers, Also the add coolant light is on. The resivor is full and i know it is circulating through out the system. The heat is not all that hot. I know there has to be a saftey sensor or something shuting the car off. Any and all help would be great. thanks.

It almost sounds as if the vehicles theft deterrent system is shutting down. Is your vehicle equipped with a theft deterrent system ? If so there's several things that could be wrong or it could be as simple as doing what's called a relearn for that system. Attempt to restart it, once it starts then dies leave the ignition switch in the run position, if equipped with a theft system ( check your owners manual) there will be a light in the instrument panel that will begin flashing , while leaving the ignition switch in the run position wait for about 10 minutes, the light SHOULD stop flashing. Turn the ignition switch to the off position and attempt to start it. If it still bothers you're either dealing with something deeper or different type of a problem. Good luck.
you might want to chk. the crank sensor and or cam sensor. sounds more to me that it could be fuel problem. chk. fuel pressure. pump could be on its way out. don't be fooled by hearing the pump running as they sound like they are pumping but there not, at least not enought pressure to keep it running. pressure should be around 50 p.s.i.
