need help 350 vortec shuts off

[layingC10nK5]

i got a 1996 350 vortec in my 2door tahoe that cuts off when i get to a stop. it takes about 3 tries to get the truck started, it idles and runs good but ass soon as you go to stop it it stumbles and shuts off. i read on another forum of the same problem, the guy replaced his fuel pump (i was going to do that tomorrow) and same problem. i checked all the vacum hoses and compared it to my brothers 2door tahoe and they all seem fine, could it be my fuel pressure regulator??? any help would be great thanks in advance.
