PONTIAC GRAND AM COIL PACK PROBLEM

1993 Pontiac Grand Am

I have a 1993 Pontiac Grand Am that will run for about thirty minutes or so then when you kill it it will not start. I have replaced the fuel pump fuel filter, ignition module, coil packs and coil pack cover. I have also replaced the fuel pressure regulator still the same. I dont know what else it could be. I also know if you put some cleaner in the breather it will fire right up and run. I am stumped so is my mechanic. A little help would be very much appreciated.

Ok there is also no service engine soon light on. How do I read the codes if the light came on? Without getting a machine.
