On 2 separate occasions approx. 1 year apart i was driving long distance from san diego, ca to nevada and idaho on interstate 15. on the first occasion (6/4/04) the vehicle lost all power and stalled approx. 60 miles south of salt lake city. was able to restart and drove approx. 5 miles when vehicle stalled again. this occurred twice more and i was unable to restart after the fourth stall. vehicle was towed to jaguar dealership in salt lake city and kept there for 5 days. the service rep stated they could find nothing wrong but ultimately replaced the fuel pump. the vehicle was under warranty at that time. the second incident occured this last week (5/31/02) and was identical to the first failure except this occurred approx. 25 miles south of las vegas and the vehicle would not restart after the 2nd failure. vehicle was towed to the dealership in las vegas. they again could find nothing wrong. i was told by the service manager that because they could not duplicate the problem in the shop that my only alternative was to for them to take the vehicle on an extended road test at my expense. they did not feel this was a warranty issue because they couldn't detect the problem with their diagnostic tools and so it was not related to the first incident. i did not feel that i should pay them for the extended road test because the problem should have been covered under the warranty. i retrieved my vehicle and returned home.
