Cadillac Repair: Car Dies Unexpectedly, crankshaft sensor, battery cables

Question
I know this is a "Cadillac" topic, but there are none for Buick. Hope it's OK to post here. My 1992 Buick Century (V-6, auto trans) dies without warning (no chugging or missing first). Doesn't matter if I'm going uphill, downhill, accelerating or cruising, low speed or high, it just dies. Sometimes several months without a problem, sometimes 2-3 times/week. I pull over, let it sit for a minute or two, then starts back up. Runs excellent otherwise, and car has had excellent care by previous owner. Any thoughts would really be appreciated. Thanks in advance!

Hi Larry, You should repost this question to the chevy or pontiac heading because they have cars there that might use the same engine as you have. You should also tell them what the engine size is because there are alot of V6 engines out there and they may not know what yours should have eithor. About the only things I could recommend are running the engine and then under hood moveing differant wireing harnesses around. Be carefull near the serpentine belt and accessories area. Tap on the engine near the crankshaft sensor. If bad it will cause the engine to quit. Check all the engine grounds and battery cables for being clean and tight. Take the ECM down from behind the glovebox area and tap on the 2 flat side with your fingers with the engine running. A bad soldier joint will cause the engine to quit. Those are my basic checks. Maybe the other guy has experriance with the ignition coil modules failing on these engines and will tell you to replace it and the problem will be cured. There are other things to check but since it acts up so sporatically now it would be tough to fix. Bill
