1999 Ram 5.9 stalls antone have an answer
Ok, my 169K dodge ram sport 5.9 stalls after about 30 minutes of running. I have replaced the CPS and Distributor pick up coil. I cleaned all the grounds and it still stalls. I drove it yesterday and after a good 30 minutes it drove fine, so I parked for 30 minutes and then after another ten minutes of driving it stalled. Like everyone else I get the dash crash and a "No Bus" with a check engine light, but no codes. I left it by the road and after about an hour came back and it restarted as it always does. It only ran about 300 yards and died again. This time we went and got my other truck to tow it and upon returning in about 20 minutes it restarted but we towed it anyway and on the way it stalled under tow. So it seems like the longer the cool down the longer it runs before stalling. I have an appointment with a guy to trouble shoot this, but would like some input here to provide. Has anyone ever figured this out? Please help.

Possibly, but the OP already replaced two of the suspects. The other two are the TPS and the transmission solenoid assembly. The latter is easy to check, just disconnect the connector at the transmission.
It's definitely temperature related, could also be the PCM itself or power to it. Easy test is if a scan tool can talk to the PCM right after the engine died.

So that crank sensor is a real pain in the A. I dropped it in but it went backwards and hung up = I had to bend the tranny tube out of the way to get it out and then the wires on the new unit were scarred so I resoldered them and put it in and thought I had it figured out, but it did not of course work so then I replaced the ignition sensor in the distributor and the same result. I cant imagine the crank sensor being solderd as a problem.

Ok, the guy said "it was a communication problem" and I need a new PCM. He wants $1,000. Oh well niot sure he did anything to check why the PCM was bad. Anyway I see I can get a VIN matched PCM for about $225 or I can send in my old one and have it checked and then refurbished or replaced for $225. Thoughts on what to do? BTW they want $600 for the PCM and $300 to program in the Vin.
