I have a 2003 Dodge Ram, 4 door, 4 wheel drive with a 4.7 motor
The truck will stall out somewhat randomly .. sometimes when I turn the key to start it will just cut it short and will stop cranking, sometimes pulling away from a stop sign or red light, most commonly it will do it on high speeds and an incline or when trying to tow something heavy (another truck, heavy trailer, etc)
When it stalls out at ANY of these times, all the gauges stop dead where they are for about a second then drop completely, the square indicator box around the gear you are in disappears but all the letters (P, R, N, D, etc) all still show just without showing which gear you are in. In order to start, you need to put the truck into 'P'ark, turn the key off then turn it will start again, that is the only way.
So far I've tried new fuel pump, new crankshaft sensor, new PCM, new ignition .. have had the vacuum lines checked for leaks (and none), cleaned the TPS and had it tested (which tested fine).
It seems to be electrical related but I am not sure anymore, no garage around can figure it out, it is not throwing any codes.
Any other ideas out there?
