05 WK Bad Fuel Check Valve?

Been having some issues with long crank times for the last few months and I finally got a fuel gauge on it tonight. Turning the pump on (accessory) the pressure shoots up to about 58psi I then immediately turned the key back to the off position and after about 45 minutes to an hour it drops to 35psi. Does this sound like a bad check valve or would I loose all pressure if the valve was bad? This is on an 05 5.7 WK thanks in advance guys!!

They replaced my fuel pump when I had the same problem.

I appreciate the reply that makes it a little easier to dump a few hundred dollars into a pump hoping it will fix the problem!!
