1998 Mustang GT. Recent tune-up, new plugs, all new wiring etc. Seems unrelated, but my car just stops, then won't start if I let fuel level get below certain markings. At first, I could go down to approx. 1/4 of a tank without problems. But once there if not refilled, the car would just quit (feels like fuel problems). Once fuel added, tank refilled car would start fine, then run fine, as long as I stayed above 1/4. Now the problems occurs earlier. When I reached 1/2 reading I would have the same situation. Now, I can only let it get down to about 3/4 before the problem arises. Again, it just stops running (seems like fuel problem), once I add gas and refill then it runs fine. I would like to know your thoughts on the problem. What major replacement parts might be needed, and approx. How many labor hours would it take a trained, certified mechanic to repair. I will take to my local gas station, who has worked on the car for many years, just want to get 2car pros thoughts ahead of time to understand what the problem and expense might be.
Do you
have the same problem?

I think it's unusual for these symtoms! 1/2 tank 3/4 tank? Test fuel pressure and check tank pressure transducer.

Agree these are unusual symptoms, that is why I inquired of 2 car pros. Will conduct the trouble shooting you suggest. Beyond that I did ask, "What major replacement parts might be needed, and approx. How many labor hours would it take a trained, certified mechanic to repair? I suspect it will end up being the fuel pump, or perhaps the transducer as you mentioned, therefore what ballpark number of hours (as previously asked) might it take for a trained, certified mechanic to do the repair?

Perhaps three hours, if done fast 2. Parts are the pump, transducer, or fuel lines, on of them might be clogging. Changing a pump goes faster if it's brought to the garage with only one gallon of gas, but seems you wont be able to do that!

I appreciate your initial response, and your further info just provided. Very helpful. As you note, will not be able to go there with tank low, but will deliver and proceed as we have discussed.

Thank you for your help.
Another instance of being provided good assistance by 2 car pros participants.
