My dodge b1500 1997 van 3.9L 6cyl. The van cuts off-replaced many sensors any ideas?

why don't you have the computer scanned on it its free,and it will keep you from buying parts for it that you don't need,you can replace every sensor on it and still not get it right,seen it happen a few times,auto zone or advance will scan it for free,then you,ll at least know,your going to wind up replacing parts on it that it don't even need,more or less wasting money on it,good luck with it and merry x-mas.
