When the vehicle is hot, does the Starter turn the engine over? If not, your starter is being affected by Heat soak, and you must replace the starter. If the starter does turn over the engine, you have a sensor that is failing due to heat soak, or your ECM is failing when hot. This is much more difficult to diagnose since each sensor will have to be monitored to find the faulty sensor.

sounds like your coil is getting hot then when it cools down the engine re starts check coil look for hot spot or touch it see if it is hot it should be cold.

Sounds like you may have the solenoid wire end touching the power wire, causing the starter to run constantly. If not, you may have a bad ignition switch.

After driving for 25-30 minutes, the car won't start for about 3 hours


Any chance you've got 'Titanium' spark plugs. We had this same issue, and found it was caused by a mechanic replacing our plugs with the titanium ones. If they were hot, they didn't ignite properly during startup. If you let the car cool, it would start right up (~2 hours). Changing the plugs for good quality old-style plugs and the problem hasn't occurred since.
