1991 XJ-6 - Had car since new. A few months ago, car stalled when running for about an hour. Would run again when cooled down, but when it gets hot, just sputters and hardly moves. Mechanic checked fuel pressure - low - replaced fuel pump. Seemed to work okay. ALso all plugs, wires, rotor, dist. cap replaced with Jaguar parts. Last week when running on very hot day, car stalled. Similar problem - cools down and will run again, but quickly stalls out. Cool off and starts. Had it towed home, and of course after it cooled down, was able to start easily and drive into garage. Any ideas???? Car is not reliable and since my wife drive it, she has not driven it since last week. Any thoughts on this are much appreciated. Bill
