My 1999 Saturn Sl2 runs just fine but when I come to a light or a stop it shakes and then shuts off. It just started happening today. What could be causing the problem?

IT says
failed egr position sensor
open or short circuit condition
failed egr valve
failed egr pressure sensor
failed egr position sensor
When it shuts off I am able to restart the car right away.
I haven't had any trouble starting the cars in the morning either

The P0133 is most likely a bad o2 sensor in the exhaust manifold that would be called the upstream sensor. Your code P0404 and you say it dies when coming to a stop makes me think that the egr valve is carbon up and sticking open and causing the engine to die.I would remove the egr valve get a pocket screwdriver and see if the egr pintle is sticking closed it should freely push down and then push it all the way till it bottoms out and slowly release it and see if it sticks open. Let me know what you find.
