Welcom to HAN. The first step in fixing this problem would be to get the CEL code and find out what's triggering it. This link will show you how to do that. Having this code or codes will give you a direction of where to start looking.

Also when you're attempting to start your engine does it sound like it's trying to start? or is it just turning? do you get backfires?

Are you moving when your engine "stalls"?

But gun to my head, if I had to guess bassed on what you've said, the first place I'd check would be your fuel pump.
