2000 Pontiac Bonneville
2000 Pontiac Bonneville starts but stalls out after
about 20 minutes whether you're driving or not
security light flashing..
The security system is shutting down the engine. You'll need to be towed to your local GM Dealer for repairs. Don't waste your time on the magical relearn procedures that everyone talks about! They won't work in your situation! Hope that helps! Jim
