Assuming that you aren't over-heating, check the fuel pump. My 1999 Taurus used to stall/ refuse to start when it was hot due to a faulty pump.
A very low idle can cause a 97 Ford Taurus to stall. Another reason for stalling may be transmission bands sticking, which does not allow the transmission to come out of gear on idle.
Stopped up exhaust.Cat converter is bad and blown back into muffler causing stoppage.
My girlfriends 97 was doing the same thing....it turned out to be the ignition switch.It started to stall intermittently (once every couple days)then yesterday it would not run at all unless you held the key in start position. Take a test drive and giggle the key to see if it shuts of.
Your charging system has failed, probably the alternator.
There could be a few reasons why a 2000 Jeep Cherokee would stall in stopped traffic. There could be a fuel line clogged or there could be a bad spark plug.
The idle for the 97 Taurus could be too low. The transmission bands could be sticking some as well, not allowing the transmission to come out of gear during idling.
Almost classic example of fuel filter gone bad.
I had that same exact problem with a 1995 Jeep Cherokee, and it was indeed a bad oxygen sensor. Relatively cheap repair too.
This question actually refers to a Mazda "6" that stalls when in the stopped position. Sorry about the miss printed info.
It means the engine stopped running.
If you leave a horse in a stall for any amount of time you cannot. Pooping is a natural action and cannot be stopped.
