I stopped in a shopping center and shut off the engine. After a short while I tried to start the engine and it would not turn over, it was completely silent. After a short while I was able to restart it. The Dodge people in tucson said nothing was wrong or they could not find any problem. After much research I discovered in old data online there was a bulletin covering "no engine crank or no engine start due to electronic lock-up of the wcm/skreem". This has occurred periodically about every six months requiring me to remove the iod fuse with the key out of the ignition switch waiting thirty seconds and re-installing the iod fuse.
All of a sudden the windshield wipers and washer came on with out warning and blinded me right in the middle of a curve. Then engine quite and horn started blowing.I lost my steering and brakes.

I had just come off of highway wher I had been going 70 miles an hour.if I had been going that fast at the time of electrical problems it would been really bad as I had two other people with me. One a 90 year old motherinlaw.
