Hi all...
I have a 92 Century (3.3L V6, ~120000 miles) that will run/drive fine, good idle, no power loss, no sputtering etc. for about a mile or so then it will just completely and suddenly die. Engine dies, all instrument lights go out, no radio, no power steering, no electrical at all...dead. When I turn the key there is no activity at all...no fans whirring, solenoids clicking, etc. After anywhere between 20 minutes and an hour it will start right up and run fine. Actually, I can sit and idle for at least an hour (haven't sat longer than that idling) but as soon as I drive away from home...about 1/2 a mile to a mile away and we are dead again.
I am going to take it into the shop but would love to hear what others think could be the culprit before I foolishly okay tons of tests and repairs that don't fix the problem.
I am adept enough with a multimeter to do some testing if pointed in the right direction...just not sure where to start with this.
Thanks so much....

Engine stalls or RPM
fluctuates at idle up and down or dies near idle.
This problem is commonly caused by a dirty automatic idle speed control valve and throttle valve but always run a OBD2 fault code as well as the cleaning procedure. Buy a can of throttle valve cleaner (do not use carburetor spray cleaner!) from NAPA or Carquest (made by CRC chemicals) and spray it into the air intake while the engine is running, use up about 1/2 the can, engine will try to stall hold the speed up, shut it down and let it soak for 30 minutes, restart and blow out the remaining fluid, shut it down and disconnect the negative battery cable for 5 Min's to reset the base idle control
