erattic fuel pressure and cutting out rite after startup

[foxfamilycustomz95f350dsl]

are the two related?


fuel pressure bounces between 30 and 60 at idle .. and seems to bounce between
30 ans 100 psi when reving up?

took apart the fpr cleaned and reinstalled.. also tryed spring shim and it seemed to
help with my engine cutting out rite after a warm start..

i start it and its ok for around 15 seconds then it cuts out but usually comes back..

sometimes it dies out and has to be restarted..

my gut is telling me that is a short thow.. just acts like one
