6.0L loss of power

Hello, I have a 2003 F250 with a 6.0L diesel engine. I was on the way home and I had a loss of power when I pushed the gas pedal. I made it home but the next day I started the truck and drove about 10 blocks before the truck would only idle. The truck will still start but it will not go above the idle. Over the past few weeks its been stalling first thing in the morning right after its started. Give it a little gas and it fires and runs fine. The mechanics have looked at the egr valve, catylitic converter and fuel pump pressure is fine. They had a code that said the fuel pressure was low (I think) but they don't know what the problem is. They say that I might have to take it to a dealership to run more tests but that is 3 hours away. Does anyone have any suggestions of what it could be? Thanks, Dave

sounds like a smart ass commet but isnt... have you checked your airfilter ? diesels love air and if you choke them off they lose power and mpg pretty quick

It had a new air filter as well as fuel filters less then 3000 kilometers ago.

take a look at the fuel filters, just because they are new doesn't mean its clogged, FICM might need a reflash if everything else turns out fine

Once you are confident you have consistent fuel pressue, if the "dead pedal" continues, check the actual pedal assy. There were some bad ones around 03. Remember these engines are "drive by wire" so the pedal is basically just a volume control.
