BUICK REGAL SPARK PROBLEM

1995 Buick Regal • 25,000 miles

Car runs for about 12mins or 12miles then cuts off. Then doesnt start back up but does turn over when trying to start if left alone for about 10mins it starts back up. No engine light have appeared. This happens in that order for 3 days now all lights are working while cutting off. Do u have any idea?

When the problem occurs, have a helper crank it, while you visually check for spark at the spark plugs. If you have spark everywhere, use a gage and check fuel pressure. You have to test when problem is ongoing. My first thought was the crank sensor, but could be other issues?

How long since a tune-up?

Just to add, you can carry a spark tester in your glove box, it won't get hot. Don't pull a spark plug.
