My 1991 Sovereign starts and runs fine for about 45 minutes and
then the engine cuts out while coasting to a stop. It will start
up again but the engine will run rough with a lumpy/faster idle.
There are no VCM codes. If I park and let it cool down, the same
thing occurs. The problem appears to be temperature-related as
everything is good when starting from cold and the problem
consistently begins after about 45 minutes of driving.
Recent repairs include: new fuel pump and replacement evaporative
flange (used but with good electrical connectors), new CPS, new EGR
valve and EGR solenoid, new ignition amp, new coil and HT leads,
and new CTS. When I replaced the CTS,the insulation on the CTS
wires from the harness was very brittle. I replaced the connector
and wires up to the point where the leads enter the harness. I
wonder if there might be more bad insulation inside the fuel
Any suggestions of other things to check would be much appreciated.

past many months and I are quite perplexed. I did search for clues
in the archives.
