Default Where did my Fuel Pressure Go?

I have installed my rebuilt LS 5.3 in my 96 Chevy, 2wd,RCLB, 4L60E, truck.
Everything is working fine. Except, after 2-3 hours the fuel pressure in the stock fuel log is gone. Thus, I have to crank on it to get it started. It is using the stock 96 pump and it is a 2 line system with the supply and return line.
Your thoughts are?

Thanks
