{: ) The engine control module is programmed to protect the engine by disabling the starting system whenever it detects that the engine temperature is beyond safe limits. Depending on how fast the engine cools, it will resume normal starting after cooling down for a while.
A diagnostic scan tool readout can give you a quick idea about the possible causes of your engine overheating. For the meantime, as soon as you can start the vehicle after cooling down, drive the vehicle and try to turn off or minimize the loads , and avoid traffic sitting as possible, just enough time to reach home or a nearby service shop.
There are several things that need to be checked:
The coolant level and quality, and check for signs of coolant leaks.
The cooling fans,are they operating as designed? Check for fan blades damage or cracks.
The water pump could be faulty. Check also the engine belt.
The engine oil.
If the engine temperature sensor is faulty, it can also bring inaccurate signals and may affect operation of the cooling fans.
Check fuses and relays that power the cooling fans.
If you mean that it starts fine when cold, but if you stop & turn off the engine (to to pop into a shop for example) then try to restart and get absolutely no turning over, then you need to replace your battery. It has a short or crack which is expanding when hot creating your problem.
