My son has a 93 Buick LeSabre (front wheel drive V6) with about 90k on
it. Sometimes it just totally dies and there is nothing, no lights,
radio, anything. After a while it can be restarted but the radio has
lost its memory, etc.
We checked the battery cables and they are clean and tight. What else
could cause a total electrical interuption like this? It seems like
this is more common soon after the car has been started cold. It has
that chip in the key thing, but it does this with either of the 2 keys
so I don't think it is the ignition key.
have a shop the crank position sensor (sometimes called cam sensor) when
these go bad they cause similar symptoms, actually they cause all kinds of
weird things to happen. also check to see if the ground strap from the
engine to either a fender or firewall has not rotted off.
Check your cables from the alternator and check the main engine block
grounds, after you have checked everything a couple times and if you can't
find the problem take a look at the sensors, I had the exact same issues on
a non-gm vehicle, the dealer checked the wiring for bad connections, check
all major items (battery, cables, fuel pump etc.) and found nothing. It was
suggested that they change a crank position sensor and that was the fix. So
to answer your question, yes a sensor could cause this problem, but FIRST
check the wiring a couple times and if possible plug a code reader into the
car, see if there are any codes. If you use a good reader it will be able
to give real-time events while your driving. A passenger can look at this
next time the car dies.

The next time this happens flex the battery cables along their entire
length then retry. Cables can develop corrosion internally, under the
insulation, causing the vehicle to exhibit the symptoms you describe.
Look for any "swelled up" areas along the cables.
As others have noted, check all connections and all grounds.
