2007 XJ8 VDP 39K won't re-start after driving with engine at normal operating temperature won't even turn over. All instrument lights work headlights work seems to have plenty of battery power and the battery is only 18 month's old and has been checked out as ok. Instrument panel shows Cruise Not Available, Transmission Fault and Parking Brake Fault. After sitting 20/30 minutes starts and runs perfect and all Faults go away. Has anyone had this problem that may know the fix?

Thanks,

I haven't seen a problem like this where it seems heat is affecting the starter circuit. However as you have fault displays you need to do something about them as the clue to your problem may lie there. Whilst you say the faults "go away", they generate a code which is then stored. So first off, get the stored fault codes read and interpreted. If the system thinks your transmission or something is not correct, it will not allow the engine to be started.
