'92 Seville-Engine dies while driving, digital display blank
Thanks in advance for any replies. I have a 1992 Cadillac Seville with V-8, 4.9 Liter engine, with an automatic transmission. The car is not an STS, SLS or any other special type.
I think there is something wrong with my car's electrical system. Here are the symptoms:
--engine and digital display/speedometer have gone dead while I was driving in a parking lot twice in the last four days
--a different time, the car would not start and the display told me to wait 3 minutes before starting; after waiting 3 min., the car started
--the station presets on the radio get cleared back to the defaults from time to time; also, the temperature setting gets set back to a default of 75 deg. F
--the digital display/speedometer flickers briefly and then works fine for a while
--the engine sometimes sounds like it has trouble starting, but will then start and operate normally
--most problems seem to occur at or within 5 min of starting the car, but happen both when the car is warm and when it is cold
I checked the engine codes using a simple tool from an auto-parts store, and the display told me to "Set Timing Mode" or something similar (I am a novice at checking the codes). More codes may be present but may be getting deleted if the battery is getting disconnected.
Based on the symptoms I'm seeing, the battery may be getting disconnected from the electrical system or have a bad connection.
The alternator was replaced recently, and the battery should have 2 more years on left in it.

Update: I had a suggestion from someone that sounds reasonable-the car may have a short somewhere.
One fact that I forgot to mention: I could turn my hazard flashers on the time the engine died and I couldn't start it for maybe 10 minutes. If the electrical system was disconnected or shorted out, it seems like the flashers wouldn't come on--this doesn't fit with the idea of the electrical system being a problem.
