I have a 1968 Beetle. It starts fine and runs good, but after I drive it 3 to 8 miles at around 50 mph, it stalls, like it runs out of gas. It is hard to start after that and will only drive about a hundred yards and then dies again. Once I get it home and it sits for a while, it starts fine and runs good, and the whole thing starts over.
I have checked my fuel pump and it is pumping fuel. I have replaced the gas tank and gas lines and filters. Problem still there.
