1992 buick lesabre starts fine. drive hiway about 20 miles to work. after about 10 minutes in town will die while going 35 mph. starts again right away. may not happen again for a couple of days or may happen again a couple minutes later. New fuel pump, fuel filter, plugs and wires.

I was thinking maybe one of the coils. Have three coils, one for every 2 cylinders. I'll get one replacement and swap them one at a time to see. Would rather spend $50 than $150 to shotgun it. Thanks for the suggestion. Grittyone. I was thinking maybe one of the coils. Have three coils, one for every 2 cylinders. I'll get one replacement and swap them one at a time to see.
