Title says it all.
Got my fuel pump changed after breaking down a couple months back, around the end of October the Durangutan started randomly stalling while driving as well as at idle. Would get a NoBus error and it would turn over as if it wasn’t getting any gas. Sometimes takes 30 seconds and other times it would take up to 20 minutes to start back up like nothing happened. Took it in Nov 1st and a fuel return line came loose, tightened up and it’s still stalling randomly. I’m seeing a lot about the PCM going bad, but I haven’t had any other electrical issues to speak of so I’m not sure that’s the issue. Any help would be greatly appreciated as I’m pretty new on self-diagnosing but if I can fix this I’m gonna go for my left bearing next.

 

Had the same issue with a 4.7 that I redid the power steering on. I went there my whole fuse box and replaced two wires and cleaned all the ports with that electrical cleaner. Let everything dry and no more No Bus. Personally I think it was the two wires being burnt and shorting out something on the pcm.
