Just an FYI for those interested.

I had what I thought was a CPS problem in my 88XJ. Would run just
fine and then quit going down the road and not restart. It would do
this randomly.

I replaced the coil and ignition module, no joy.

I cleaned all the grounds in the engine bay, no joy.

I replaced the CPS, no joy.

By this time my wife was getting pretty pissed since she mainly drives
this jeep, cause she loves it.

After reading the TSB about replacing the CPS circuit with one that
bypasses the big connector on the firewall in front of the driver I
disconnected the connector (which is full of some kind of grease) and
cleaned all the connetions, male and female. The Jeep has run fine
since.

The TSB says that the CPS circuit encounters high resistance in the
connector which of course causes the signal to the ECM to fail.

Maybe this summer I'll reroute the CPS circuit but it's 12 degrees
outside now so I think I'll wait.
