There are no light that come on on the dash. I was driving it and while I was stepping on the brakes I was about half way down when the engine cut off and after I got it started again I stepped a lil on the gas and it died again. Once I got it started and rolling it wanted to die as I was slowing down.

Check for vacuum leaks and take a fuel pressure reading.

These models are also known for engine wiring harness faults. And check that engine has good ground to car body. There's a ground strap on underside of engine. Best to get it checked out with 'star diagnostics'.
