need daily driver help

My daily driver is a 99 gmc with the 5.3. Lately it has been hard to start warm. Its starts just fine after sitting for several hours. Fuel pressure is at 45 pounds and bleeds to 40 right after shutdown.

Im not a fuel injection guy but does this sound like a pump problem? Shouldnt the pressure be about 60-65 pounds?
