2000 Dodge Intrepid broke down dont know why

I would like to ask the question of y my car brokewown and wont start back up for me. I was on the interstate going about 80 then I got cut off and had to hit my brakes and pull into the fast lane then when I tried to speed back up my engine killed on me and I was stuck in the median the engine turns but doesnt turn over and start just cranks. It wounds fine no irregularities but wont come on. The advice I got from some cooworkers was that it mite be my fuel pump or I mite have a failsafe switch to cut my fuel off if it got to full im not sure wat any of that means I konw nothing about cars. Could you please give me some insite or answers? Thank you very much greatly appreciated!
