Hi all,
I am looking for some advice on where to look next. My 2500HD (8.1L) had been doing great. Last week I was towing my trailer, pulled into a rest stop and left it running for a minute while I did a few things. I noticed that it would start to die (like it was running out of gas) then it would rev up and then idle again. When I got in and stepped on the acellerator pedal, it would cough and sputter and then die. I got it running and then again, the same thing. I finally towed it home, replaced the fuel filter and started it up again. The same thing. Any ideas on where to go next? Oh and its fair to mention, NO CODES, no check engine light, nothing. HELP.

Thanks in advance, Kevin
