alright, i know it has to have something to do with going into closed loop. it is fine when its cold and when it warms up, even if its just from the sun it will die... i cant figure out what would be doing this.... what would shut off the engine in closed loop if it was going bad?

When it doesn't start, you need to check for injector pulse with a 'noid light, and check for spark. My guess is you don't have spark for some reason. Why? It's too hard to say. Can't really diagnose stuff over the internet. Especially with no real information.
