JAGUAR XJ40 ENGINE PROBLEM

1991 Jaguar XJ40

Engine Performance problem
1991 Jaguar XJ40 6 cyl Two Wheel Drive Automatic

someone ran car out off petrol. Ever since car starts off key runs perfect for 5 seconds then runs like its missing the odd backfire. Then when engine gets to normal temp (even though it sound and runs terrible) it dies and wont start again untill engine has gone cold again. And youre advice would be very apreciated. Thanks very much. Wont rev up properly.
