Answer
Hi bruce:

well it can be a lot of things.. does it start right back up easily when it stalls out? when  it stalls what happens? does it chug buck and sputter then die? Or is it like someone turnes the key off? It's eithere a spark issue or a fuel delivery issue.. it can be a fuel pump or a crank shaft positioon sensor.. It can be a bad ground wire connection. has any service engine soon lamp come on at all?
