While driving gas pedal quits working and car dies when i stop

sorry but ask a local mechanic to have a look for you ,something amiss here and i suspect that who ever sold you the car knows what the problem is and its a big job to repair so sold the car quick ,,,,do the same ----

Have you checked fuel pressure?

There has to be a story about that situation

Share it with us ---the long version & what possibly
could we do for you ,IF --you never work on your
own cars,if that is the case

The fuel pressure and fuel system needs to be inspected.

Check for vacuum leaks.

Have someone feather the gas pedal while you listen carefully to the engine. If the leak is bad enough you'll probable hear it.
More than likely, it's either a vacuum hose or the o-rings under the intake manifold.

Hope this helps!

It sounds like your fuel filter is clogged. Try changing it.
