Engine Performance problem
1999 Land Rover V8 All Wheel Drive Automatic 128000 miles
My Land Rover started sputtering today on the highway. I would give it gas but it wouldn't go faster then something would happen and it would start to pick up speed. I finally got off the highway and the problem continued until it finally stalled. It restarted for me about 5 minutes later but stalled again shortly up the road. What could the problem be?
