i drive a 05 6.0 psd and on my way home from work yesterday my truck started doing some crazy stuff....egt's jumped and power went way down. got off the highway and truck would barley move, i am using a triple dog so i pulled the program out incase it had to be towed it started back up with a very rough idle (shook the truck) and little to no power i mean 5 mph max. stoped and sat with the hood open for about 20 min while i was on the phone with the dealer. after the 20min it started up and ran fine put the tune back in and all was normal. the dealer told me today it was a bad fuel pump......this sounded kinda odd has anyone had that issue? or can anyone verify thats what a bad fuel pump would do? kinda worried cause i have 96000 miles and would like to have it all fixed before the warranty is gone
