2004 Dodge Ram 1500 cruise control problems

My 2004 dodge ram would intermittently drop the cruise control when I hit the drivers side down button. I took it to the dealer several times and was told it wasn't throwing a code and they didn't know what was causing the issue. Several months ago, after parking my vehicle in the garage, I woke up to discover the drivers door had caught fire. It sure looked to me that it started on the circuit board inside the door. The vehicle was totaled.

2004 ram 1500 5.7 hemi stalls at low engine speeds, often at stop signs, traffic lights, or parking lot maneuvers. Will usually start immediately back up, sometimes requires slight accelerator pressure when cranking in order to obtain self-sustaining engine speed. During decelerations, engine RPM is erratic and will often encounter a transient drop in rpm's to approximately 400 RPM before engine dies.
