Buick Rivera dies while driving and won't restart.
I have a 1997 Buick Rivera Supercharge. It runs beautifully while its running, but then it will suddenly shut off while I'm driving and will not restart. The shop I took it to can not figure it out. We have replaced the fuel pumps and that made no difference. This is a random event and can happen anytime without warning. Everyone is perplexed. Any ideas would be very welcome.
