I have an update. I drive the same route to work everyday but I dont always take the same car, but my dealer suggested I keep a log of when the problem happens. So for about a month I took the mustang consistently and found a pattern.
 
I fill the take at a gas station near my home and drive about 45 minutes to work by highway with minimal stop lights. When I drive home, about 15 minutes into the same route back, I hit a series of lights, if I miss the lights and have to press down on the clutch, the car stalls. My tank is about 7/8ths full. It will now stall every time I press the clutch, even when shifting! It continues until I get home, which is about another 30 minutes.
 
If I make the lights on the return home, I dont have the problem. It only happens at 7/8ths of a take and for that one journey. When I get home, cool the car, it runs fine.
 
Recently, the symptoms got much worse. It would stall and not restart. I would have to pull aside for 15 minutes and chug home. It would sputter and the failsafe light went on. The last time it happened, was the first time the failsafe light came on for stalling and the "not starting" problem was by far the worst.
 
I brought it to the dealership and the computer codes told them it was the throttle sensor. They replaced that, and broke the throttle body bolt. (thats another story).
Anyway, the car came out running better than it was when it was new. It performs much better now so obviously there has always been something wrong with the sensor.
 
That said, I have not filled the tank yet and driven my route to work since it was fixed. So I dont know if they fixed the stalling issue or not. Since the last episode had many distinctive symptoms different from the original stalling issue, I doubt its fixed. I think it has something to do with the fuel tank. The 2005 mustang has alot of TSB's regarding the tank.
 
Fortunately my car has the extended warranty so I only had to pay a $100, plus I got those damn door handles fixed. Another TSB for those and they way they dont sit flush.
 
I will update you if the problem happens again.

Thanks fastdogs. I was waiting to hear that key word, throttle sensor. I had a strange feeling that the throttle sensor could be the problem. I dropped prower to my car last night by disconnecting the battery. This evening after reconnecting the battery and driving it for about 1 hr the car ran fine. Not sure if this solved the probem but I will let you know. Thanks for the update fastdogs.

Hey fastdogs. I have an update for you. I had my local Ford dealership replace the TPS sensor and you are abolutely correct It my a world of difference. The car has more power, the throttle response 100% better and I think that the mpg has increased. Thanks partner. Keep the Stangs rolling.

Thats great to hear. I have filled up my tank and so far no problems, so my theory is shot. It looks like it was the sensor after all.
 
I think I'm getting a lot better mileage too. Its like a new car. Thanks for the update.

Has anyone heard of this problem with the 2005 mustang by pdxshedevil

When I shut the overdrive off today all of a sudden the whole computer rebooted while I was doing at least 25-30 MPH, however the car kept running. at first I thought loose battery cable, but I again turned the overdrive off and again the system shut down and rebooted. After figuring some of what was going on I quit turning the overdrive off and the car ran fine all the way home. This is on a 2005 Ford Mustang V.6

That is a weird issue, but it begs the question, "Why are you turning off OD, anyway?" And what do you mean "the whole computer rebooted?" You need to give us more details of what happened. What lights/messages were displayed on the dash? Were all the gauges still working? From the info you provided, it doesn't sound like a computer "reboot" at all; at least not the engine computer. If that was the case, the car would've stopped dead. It may be an issue w/ the Transmission Control Module (TCM.)
 
Details, please.

I was turning off the overdrive as there was a long line of mustangs on our tour to the beach which was a bumpy winding road and it seemed that I did not need to use my brakes as much with the overdrive off (the engine would slow enough as not to need the brakes all the time. The first time it happens I heard a slight pop from somewhere under the dash and then all of a sudden all my instrument lights lit up as they do when the car is being started,my radio has to be reset as it also lost power, and it automatically restarts it in overdrive, so not knowing I drove a while longer and then again turned off the overdrive and within 5-10 minutes it did it all over again. I tested my theory one more time and it happened again. For the remainder of the trip I left the switch alone and the car ran fine.
