Actually, none of the silly suggestions you had. Assuming as you said, you ALREADY started the engine, and THEN it died. So it cannot be the spark plug (if this was the problem you will have problem starting the engine), there is really only one engine so I am not sure what is the "main engine" you are talking about, and the clutch only matters if you are experiencing problems while changing gears.
So my suggestion would be this - next time you are stalking someone, pls call an uber, your failing car and nonexistent knowledge make you a pretty lousy stalker. (Besides I suspect it's a lot more fun stalking someone with a random uber driver)
