My uncle recently left me a 77 450 sl. This car has sat for a year but it fired up and seem to run fine, that was until I got about 10 miles down the road, then it stalled. I waited a couple of minutes and fires it back up and it stalled again in a few miles. I have put about 100 miles on the car locally and ran new fuel in the car ,but I still have the same condition. A fuel pump was installed in the car about 2 years ago and approx 500 miles of driving since then. What may be the comon concerns with this car.
Thank you. odometer 60,000
