Fuel Pressure Dropping in the AM!?!?

I have been having issues with my fuel pressure the last few days. On my way to work in the morning the pressure is down around 5-6psi and I have to take it easy on the go pedal. In the afternoon when I head home it is back up to normal... which is 14-15psi on the Monitor. (Juice W/attitude) Any ideas on why this could be happening? I replaced my LP in Feb. just 6,000 miles ago.

My fuel pressure varies according to temperature but it usually takes extreme swings to see it, like over 90F and under 32.
Think it's due to the viscosity of the fuel changing.

Im in Tampa, Fl and our temps only go down to about 78f this time of year. (And then up to 98+) Thanks for the idea but I dont think this is a factor! If my LP is starting to go out again I dont see why it would have this pattern!?!?

What fuel pressure gauge are you using? I've had sending units starting to go out that would exhibit similar symptoms.
