Thanks for the suggestions. The car had plenty of gas and since the tow truck driver started it, it operates completely normally. I called 3 local shops and the Lexus dealer and all of them told me that this may be difficult to troubleshoot because the car is now working. All said that the engine immobilization system has nothing to do with it and that the wiggle on the outlet probably had nothing to do with the problem going away. Apparently there are several sensors that could shut the engine down and the plan is to have a shop try and shake wires/inspect components to see if they can duplicate it. If they cant find anything, then I'm faced with wondering when it will happen again. I use this car to travel between Fresno and SF which is 180 miles of freeway with services not that available so I may be faced with trading it in. Too bad because it has been an absolutely trouble free vehicle until now. I have done all services including timing belt/ H2o pump. All shops here in Fresno recommended taking it to the dealer so that is the plan. The dealer has treated me pretty good and they give my wife a brand new loaner car. Their trouble shooting estimate is $108.00. I'll let you know what they find or don't find.

1999 RX300 AWD 158000 miles. I was driving at 70 mph for approx 1 hour when the engine failed. The symptoms were a loss of power, decrease in speed, no warning lights. I was able to steer off the freeway and then all warning lights came on and the engine was off. I attempted several restarts and the engine would turn over and sputter but then die. After AAA arrived, the driver "wiggled" a small socket located beneath the fuse panel under the drivers side dash board and the engine started and operated normally. There was plenty of fuelin the tank. I was able to drive home (70 miles) with no problems. I have tried "wiggleing" this outlet to duplicate the problem but the car works normally. Any ideas??? I suspect the engine immobilization system.
