can you duplicate the stall with a fuel pressure gauge attached to see if it is a fuel pressure loss?

Ben trying to do that. Put fuel pump in last week, drove it with no symptoms, four a week, did it again today. cleaned all ground cables and pos leads. checked relay, checked out ok, but replaced it. checked vacuum at pressure regulator, has vacuum, but should pressure psi go up or down with line not hook up.
