I was driving home doing about 60 mph and came up to a red light. When I I stopped at the red light there was no problem light turned green and pulled away next thing I know the engine started to chug. I was thinking that I ran out of gas but it didn't die just total loss of power. Well I kept it going for about another 1\4 mile and hit a hill it wouldn't even pull the hill.so I pull over and it is just idling but with a rilly bad chugging so to try and save the engine I turn it off then about 10 second's layer I start it agien. Still chugging and it won't stop so I turn it off agien well that's the end of the car. It will start but dies immediately. And now there is this weird humming sound back by the gas tank that wasn't there before the car did this. I'm thinking fuel pump but hopefully it is just a clogged fuel filter. But the end of that trip to the store ended with the car getting towed home and the pack of cigarettes I bought may end up costing me way more money than I ever thought about spending.

I drove my car home from work cut off the engine. Went back out to leave again and the car would not start. the radio and lights did come on but after awhile the total car was dead. I was told this could be the fuel pump in this type of car.
