7.3 shutting down

ok my sisters b/f said his 99 7.3 just shut off when he merged onto the freeway yesterday...well he replaced the cam position sensor and thought it would be fine and then today he said it would sputter a little and than eventually shut off...when he pulled into work it shut off again when he put it into neutral...his dad is taking it into the dealership tomorrow to try and figure it out but i told him i would come ask you guys so his dad can go with some ammo!! thanks in adcance

Trucks also have a low oil presure sensor that shuts them down.

I have heard of people getting bad new cam sensors. I would try one more, and then start looking into other problems. You might also try posting this question in the 7.3L section.
