Other Fuel System Pump problems of the 2002 Jeep Grand Cherokee

I was driving when all of a sudden my vehicle cut off in the middle of traffic. Also, Sunday morning I was driving to church when my vehicle would not start. I was told my a mechanic (not on duty) that it could be my fuel pump, wiring or catalytic converter. Please look into this matter as soon as possible.

The engine stopped while driving took it to a mechanic and they said all fluids were filled it was just a "bad engine" I paid 2700 dollars to have engine replaced . The truck still wasn't running right it was having trouble starting took it to the mechanic and he changed the fuel pump 700 dollars . The truck still dose not run right ive had brake lines replaced that broke with no impact or accident ive been told the master cylinder needs replaced there is no brake pressure my wiring is messed up and now both my brake lights are out ive checked fuses and bulbs the truck takes several tries to start it its in the shop more than I drive it its dangerous and I never know if its going to stop in traffic or if people behind me know when im trying to stop I have 6 kids I drive to school every day and I worry about their lives every time we have to get in the Jeep I feel like buying this vehicle was a huge mistake.
