1999 slk230/ 2008 Infiniti FX35
1973 450SL-Drove about 60 miles at 60 to 70MPH and when I exited the highway the car stalled on the exit ramp. Would not start (acted like it was out of gas). Gas guage showed 1/4 tank, but it would not turn over. Got a couple of galons of gas and poured in it and the car started, but would not stay running if i let off the pedal. After a few minutes the engine smoothed out and it ran fine. I continued on to my destination and when i left to return home the car started right up and ran perfect the whole way home (another 60 miles). When I got off the highway the car stalled again and I had to repeat the above scenario to get it home. Now it is running fine again. Help!
