2004 Impala Stopped Running on Freeway
My 2004 Impala SS, 3.8 Supercharged motor, has been running fine for 325,000 miles, but 2days ago while going 60 mph, very quickly lost power and regained it almost instantaneously. Drove home another 10 miles without incident. Yesterday after driving only 5 minutes, the engine shut off while doing 65 mph. Coasted to the side, restarted and drove another few miles in stop and go traffic and a drive thru then while sitting in a parking lot is started to run rough like I was running out of gas (I have a half tank) and finally stopped running. I restarted and it ran very roughly like it is not getting enouhg gas for about 30 seconds then died. It would not restart, but it is trying to fire. I had it towed home. This morning, I started it, it ran fine for 2 seconds then ran very rough like out of gas for 2 seconds and stopped. Any suggestions on where to start? I'm guessing Fuel Pump or Fuel Filter.
