One problem related to ignition module has been reported for the 2001 Dodge Ram 1500. The most recently reported issues are listed below.
Dodge Ram 1500 continues to stall while driving at low speeds or braking to slow on highways. The loss of all power steering and brakes occur until the truck can be re-started. The problem seems to be heat related since it occurs most often when the outside temperature is over 80 degrees and the car driven over 1-1/2 hrs in duration. This problem has been occurring for the last three years and the manufacture has made many repairs but none that has fixed the problem. They have changes sensors, throttle body and then cleaned same. Changed air filter but nothing has corrected the problem. As recently as last month the dealer had the truck for three weeks and could not find a single thing wrong. I can tell from the internet I'm not the only person having this problem. It most be fixed or loss of life will occur.
