One problem related to gasoline engine has been reported for the 2005 Dodge Ram 3500. The most recently reported issues are listed below.
I was driving my pickup in my driveway, and had to place the vehicle in park and exit the vehicle leaving the motor running. About 10 seconds after exiting the vehicle it stopped running. I have seen on internet forums that this is a relatively common occurance, and it unfortunately happens on the roadways so I feel so far I have been fortunate.
