Thanks for all the replies. I pulled the covers off of the steering column and noticed that the wires leading to the solenoid that releases the key were really tight. My strain relief probably moved. Anyway, I reseated the connector and everthing started working fine. Several miles of driving revealed no other issues.
I reworked the strain relief and will drive it a few days with the covers off. If it acts up again, the ignition harness I just replaced is probably flakey.
Once again, the replies are much appreciated. This forum is awesome !!
