Engine runs fine but dies every now and then when you come to a stop.
Engine vacuum is 17-20

Borrowed a fuel pressure tester from Autozone.
KOEO 39-40 #
Engine running gage goes to 30#
At idle or when revved. Goes up and down maybe 1# as you rev it or return to idle.
Let engine idle for 15 minutes sat steady on 30#
Remove vacuum line from FPR - stays at 30# - engine does start to die.

Any suggestions?
Check for leak on the injectors when they're on
