Need help!!

So about a few weeks ago comming home from my brother's house i notice my ka24de making a knocking noise comming from the head and my oil light was on. I am not mechanic so i googled it. Seen another 240 on youtube making the exact noise and he said it was the timing chain guides. Well im hoping it is the guides but th next day while driving to work my car idles pretty high and dies out on me at a traffic light. Starts back up right after and i made it to work and home that day. I didnt bother driving my car for a few days but i drove to work again that week and it died out but started again right after. At the next stop light my car dies again this time it doesnt start back up. It wont turn over either. My motor isnt blown nor am i leaking anything. Checked my oil and my oil was good. Im just really stuck on what it is. If anyone else can help that'd be great
