Engine Failsafe mode-no start

Hi All,
I read as many posts as I could but I don't seem to be able to find an answer. I have a 01 XJ8, and after driving for 30 min or so, if I stop, go into a store and then return, the car will not start and the engine failsafe mode is displayed. Engine will turn over just fine. I tried turning off the cruse control which did not help. I read that maybe the break switch? If I park the car over night, it starts just fine with no engine failsafe mode indicator (engine cool). Heat related? I had the battery checked and the charging system checked, to no avail, it checks out fine. Took to a repair shop twice, so far they can't find anything (but is sits and cools off before they work on it). This is getting $$$$. It's driving me nuts, and I can't safely stop anywhere with out this happening. HELP!

Hi I have the same problem with my '98 XK8 not starting immediately. The mechanic advises that the original models were built with one type of piston lining which was replaced in later years. The old type isn't air tight allowing same to flood (petrol) hence it will not start. The plugs need to be removed, oil is dropped into the cylinder to form a seal , then it will restart. But as you say grrrrrrrrr annoying and something of a design fault which one would not expect from a Jag. My XK had to be RAC recovered to the garage this morning for same problem.

My apologies. I was thinking of the brake switch in the XK8. You're absolutely correct - the brake pedal is in the cabin of the XJ

I did the same thing, shift to neutral and it starts. I had the battery- charging system checked ...OK, when this first started to happen. New battery installed last year Sept. Only happens when temp is 75+ and car run for more that 25 min. Below 70...it never happens. Is there a switch somewhere (trans..etc) that could be causing it not sensing that it is park? Got a error code of P0652?
