Did this stalling ever happen before? Did this stalling start right after the first start? Your going to have to see if any of the fuses blew. You'll need a 12 volt test light to check each side of the fuses, do you own one? The engine is all run with sensors, one may be shutting off intermittantly, read about how it works, testing fuses, and how your engine is diagnosed and repaired. Maybe this would have happened anyway. Don't feel bad, this type of thing happens all the time, if you need help understanding the codes, let me know, if you want you can e-mail me, ok?
