Might check your fuel filter if it has not been changed in awhile, dirty ones can cause weird issues..

If you go to the usercp in the top menu and fill out your SIG in the left menu with the specifics about your truck it will show up like my information below and when you ask questions people automatically know what you already have...

Good Luck with that...
