Default Is this a sign of a bad fuel pump?

Hi guys. I posted in another section (https://ls1tech.com/forums/pcm-diagn...d-cms-cks.html) about some issues I was having with my car lately and I was told that my fuel pump might beon its way out.

Does this sound like a fuel pump issue to you and is there a way for me to verify this?

Hook an external fuel pressure tester to end of rail. Pressure should be at 58
