1998 Pontiac Sunfire

For the past few weeks my car has been having some serious problems. When in park (idling) the needle drops and jumps and then rests on one and then repeats the jumping and dropping again. When I put it in reverse it has been dying and until today I was always able to restart it by pushing the gas and turning the key. I was driving down the road today and my car completely stopped working. My breaks wouldn't work. My gas wouldn't work. My car would not restart. My oil light came on and my battery light came on and all of the needles for my gas, mph, etc stayed where they were when the car died. I can't trust many mechanics in Arkansas. What do you think is wrong with my car?
Thank you,
