Turns over but will not start

I was driving one day and when I went to turn into a store it keep turning off. I had to restart it about seven times just to get into the store. My dad saw that it had a crack in the ignition coil so we put a new one in. It ran for a day then would not start. So then we thought maybe it was the starter so we put a new one in then it still would not start so we looked at the distributor cap and rotor bug so we got new one and put them in and it did not start again. So we thought maybe spark plugs. So we got new ones and still will not start. Then we turned to the gas and got a new fuel filter and still would not start. Anybody know what else it could be?
