I have a 2000 Mercury Sable LS, 3.0 V6 that when I come to a stop it will slowly die. I pulled into my parking space this morning at work and it just faded off. It usually fades off right after I shift it into park. I can restart it right away and it starts no problem. Often if the car sits and idles it will make sounds as if it is going to shut off, because it doesn't have fuel or something, but then comes back to life. It may do this several times in a row, then idle fine, and repeat this the whole duration it's idleing. Of course this doesn't happen every time I stop so it is hard to diagnose. I have had a mechanic test to see if they can find the problem, but they said there was nothing wrong with the fuel system. I'm not so sure there isn't a problem with the fuel system, but are there some specific diagnostics tests I should have done or do you have any suggestions on where to start to find the problem. ?

We all here could take a stab at it and be wrong, with no engine light on and the car not actually right here, it could be a hundred things and I dont want to point you in the wrong direction,

what I can say is your shop should have held the car and told you they may be able to find the problem if you were willing to pay diagnostic time, this enables the tech to properly diagnose the vehicle without replacing 100 parts which it seems like people do now.
Find someone willing to take the time with it as long as your wiling to pay, my rule of thumb is check check and recheck before replacing anything.
