Only five minutes after starting car in morning, engine rapidly lost power and quit completely while in 60 mph traffic on heavily traveled interstate 526 in charleston, sc. coasted car out of traffic lanes to side, a very dangerous location on elevated roadway. had car towed to audi dealer, who said they tested and found fuel pump had failed. they replaced fuel pump and engine seems to run normally now. in four decades of driving i've never had a fuel pump fail. this one put my wife and me in jeopardy due to the sudden and complete loss of engine power in middle of fast, heavy traffic. we were lucky to get out without being hit by oncoming trucks & traffic. *tr
