Got a 1995 Lasabre with intermittant electrical issue - Pattern usually runs like this - speedometer moves to the right (about 70MPH - car stays steady), lights blinks, then engine will die. I'm usually able to restart, but not everything immediately comes back (interior lights, ABS lights on dashboard, etc.), then everything will return a few minutes after turning off engine and removing keys. Looks like all computers are resetted on board and I'm unable to find a short, blown fuse. Battery has been replaced recently but had this problem before then - do I start with alternator, ABS.

Any other possibilities?
Thanks,
Mike
