Losing Rail Pressure

This problem developed this morning on my way to work. Im not exactly sure what attributed to it could have possibly been the -4 temperature but its hard to say. Anyhow the truck idles and runs fine until the fuel rail pressure hits around 22 or 23 kpsi and then it falls flat on its face to 3 kpsi. Im kind of hoping its a fuel filter or something simple like that but didnt have time to get one after work tonight. I typically run my tune on stage 3 and even tried setting it back to stock and the problem still occurs. If anyone has any insight it would be greatly appreciated. I did a few searches on the forum and couldnt really find anything similar to what mine is doing.
The truck is a 2003 LB7 with a edge evo tune on it
Thanks

This is why I carry a FF under my back seat. Possible you got a clogged FF or bad fuel.
