No good idle on restart of warm engine
So after an effortless start first thing and subsequent drive; I get to a destination, try to restart the car after a while of sitting it starts, fires up but fails to sustain an idle without throttle input.
in a few seconds, idle is sustained again?
2007 XK with 81K miles
Is my MAS failing?

I SORT OF had a problem like this in my P/S Mustang; It'd start and run fine, but if I shut it down for more than five minutes it would barely crank over. If I waited more than 15 minutes it'd start fine.
The problem was that three of the four power valves (dual quads) were leaking fuel into the intake and going past any open intake valve and somewhat hydro-locking the engine. That made for some smelly oil, which is how I found the problem.

In addition, the day I took my car to the track, after running very hard on the track, I let the car sit for 20 minutes. Trying to start the car after 20 minutes was horrible. It sputtered, shook, and wouldn't stay running. Ultimately I could get it started and after revving and playing with the throttle got it to smooth out. Then I ran the track again, and after 20 minutes of sitting, same thing on re-start. Never got a check engine light.
Maybe as stated above, fuel injectors leak by and fill the engine with gasoline?
