Hi mdiva901. Welcome to the forum. The good news is when the Check Engine light comes on, there is a diagnostic fault code stored in the engine computer. That code will lead you to the circuit or system with the problem, not necessarily the defective part. Many auto parts stores can read the codes for you.
A common problem on the 4 cylinder engines is the camshaft position sensor. Also, if you have the single overhead cam engine and you have a fault code related to "cam and crank sync", suspect a sheared off dowel pin between the camshaft and sprocket. When the sprocket turns a little on the camshaft, it will be interpreted by the Engine Computer as a jumped timing belt, and the computer will shut the engine down to protect the valves. The dowel pin, or a jumped timing belt are permanent and the engine will not start until the problem is fixed. The camshaft position sensor very often fails by becoming heat-sensitive and will work again once it cools down. Suspect the sensor if the engine will start and run after a few hours.
