I was driving my 1990 XJS on open road, the outside temperature was 90+ when suddenly the engine stopped. Fortunately I could pull off the road and I let the car sit for about 45 minutes. Next I tried starting the car, it started immediatly and I drove about 10-15 miles and the engine quit again. I waited about 30 minutes started the car and continued for about another 10 miles when the engine quit again. I continued to stop start this way and finally got home. The car has 69000 miles and I am the original owner and this never happened before. Any help in solving this problem is appreciated; I am not comfortable taking the car on the open road.

Did this work? I'm having the same problem with my 1987 xjs and nobody can tell me what the problem is. I've spent hundreds of dollars and nothing works.

My Jaguar expert determined the problem to be the "REFERENCE SENSORS". He replaced both and my 'sudden engine stop' problem never re- occurred.
