98 LeSabre having issues with battery drain while driving. Shop cannot find anything else wrong after checking on their machines. They think I am crazy and think it is just the battery gauge now. I

SOURCE: car dies while driving

Sorry to hear about your vehicle. First things first. When you say driving, what are you ding and where are you? such as; on the highway, at a stop light, making a left hand turn, coming to a stop. Second, when you say dies , do you mean your driving, your cars "shuts off" and your stuck in the middle of the road? and when you say stays dead do you try to start it? does your radio come on? are your light on or are they dim? all these are very helpful in diagnosing the root cause of this concern. also was there any work done recently to the vehicle? if the car is running and it dies a few things could be the cause. one, not that common, your engine could be starving of fuel, fuel pumps, filters and injectors and throttle body could all cause a fuel starvation. two spark cuts out. I work for volvo and i see coils (devices that increase spark) on 98+ vehicles literally crack in certain areas and cause rough idles, choppy acceleration (stuttering while getting on a freeway) but third and most likely battery/ charging system (these are just three common flaws there are lots of other little things associated with the electronic fuel injection system and monitoring that could and may well be the cause). the way your vehicle works is the battery stores a charge and your vehicle draws from the charge what it needs. on start up its battery power until your alternator reaches a certain speed (or the computer tells it to turn on) that supplies the power to the vehicles electrical system. now that i know you have an understanding i can suggest what, giving the limited info i have, i would look for first. if there is no rough idle apparent when the vehicle is warm that suggests fuel probably is ok and so is spark. now if your alternator cannot keep filling the battery up with an electrical charge, your car could just plain turn off. now this could cause a slow cranking when trying to start the car again and it may not even start. but as to why it will come back to life after a few mins or few days is interesting. check connections at the battery because that will prevent the flow of electricity. make sure its clean of dirt and paint too. take a wire brush and clean it. also is there anything white or powder-like on the terminals? oxidation causes a poor connection. that can be cleaned with spray cleanser from auto parts stores or scrubbing with baking soda and water but thats my guess without having the car to test. please post what you find out about your car.

it does sound like you are having a problem with an alternator.

SOURCE: Low voltage, the battery runs low when running the car

What is the voltage you are reading? Is it below 13.2 or so? Also have you checked the current with the engine off to see if something else is working that should not be on. I ran across this twice while working on a truck and car. A relay that was wore out keep trying to close and would drain the battery every couple of months. Sometimes you can hear them clicking or buzzing. Touching them sometimes they are warm or real hot. But that is not a sure sign it is bad. In my Trailblaze they get hot but are ok. Another thougth is the belt on your alt, correctly set to spin it at the right voltage. I have ran across this many times lately with serpatine belts.

do you get fuel pump pressure, should be about 40 psi what about compression and spark on a saturn would be stronger due to many reasons one of which being different voltage of coils

The security system (VATS/PassKey) is faulty. You can find a great write-up here: http://newrockies.ca , it was the only thing that saved my Park Avenue.
