Just dies while driving, then "no bUS" and engine light

Yes, inside the distributor, sometimes it's called a pick-up coil.
A NO BUSS message means there's been a loss of communication between the ECM and the dash cluster. For 99.99% of these situations, the problem is either a bad ECM, a bad cluster, or a problem with the wiring between the ECM and the cluster. A bad cluster won't cause stalling. If the ECM has been replaced then you're down to a wiring issue.

dead ram
Thx for the input. I found a ground strap from the engine to the firewall that was not secure,and had hoped that was it but no cigar! I will take a hemostat and jiggle wires one by one at the plugs. If anyone has any other ideas , please post as soon as possible. I am SERIOUSLY FRUSTRATED.....lol

I have the same problem -- it causes my engine to stall while driving. It happens randomly once the engine reaches peak operating temp. I usually get it going again by pushing down on the third cluster plug on the PCM located (what a great design idea!?!?) right above the hot engine. Sometimes I have to wait till the temp drops a little. I turn the key to RUN position then push down or wiggle the cluster plug until I hear the rely click in the fuse box. Then it usually starts. I cannot seem to figure out if it's a bad connection on the plug (seems like a hundred wires!) or in the receptacle on the PCM. Sometimes it won't happen for a day or two but it always dies when I hit slow traffic. I've cleaned the contacts on both sides with no change.
Another marveous MOPAR design flaw.
I have the treatment but not the cure.
Does anyone have a definative cure for this?

I had a mysterious stall problem this summer. Long story short it turned out to be slight corrosion in the connector of the cam timing sensor. I cleaned up the connection and it went away. These vans are getting old enough that a little corrosion will start to show up. I'm going to open all of the connectors to vital components and clean them then apply Dielectric grease to block and future corrosion.
