Recently bought XJS V12 with 15K miles; driven only 1K miles since 1993. I drove the car 250 miles the day I bought it with no problems. Since then, it idles well for 30-60 seconds but then stalls
Check the fuel filter(s). Your long drive may have shaken dirt or old fuel gunk ("varnish") loose and plugged the filter most of the way. Enough fuel gets by to start the engine, but then it starves when you put it under load.
