Spark Fuel and Air. The 3 things needed for a car to start. You need control to make it continue running properly. Check those 3 things, and you'll find your problem. For spark, check coil, dizzy, rotor, cap, wires, plugs. For fuel, start with making sure you have pressure at the rail. For air, check the air filter, MAF (if you have one), and IAC/IAB valve. If it's none of those, then you have bigger problems that should probably be checked by a professional.
