Has anyone resolved their issues with their trucks dying on them while driving? I have a 2005 5.9L 2500 Ram that we bought used 2 years ago. It’s run fine up until this summer. On a hot day if I have to drive for longer than about 20 minutes, my truck will just randomly die on me. If I’m going fast (above 45 or so), it will catch itself immediately and restart. But once it’s started stalling/dying, if I have to slow down to come to a stop, it will die completely and I have to restart. It restarts just fine but if I have to keep driving slowly and stopping, it dies every time I come to a stop. It throws a P2509 code and we’ve checked the batteries, cables, connections, and every wire we can see and they’re all good. Any other suggestions on where to start? Again, it only happens when it’s hot outside (above 80 degrees).
