2003 Cuts off when hot, will not start untill cool

check crankshaft sensor

Sounds like a "HOT SOAK" problem.
Starter gets hot,it lacks power to crank the engine.

Possible "Vapor lock".

Check for engine codes.Possible bad temp sensor for ECU.

If fuel delivery is suspect ,try starting fluid into intake when "no start" occurs to diagnose fuel problem.

Has anyone checked fuel pressure cold and hot ? Check engine light on ?

Seeing as how you had a check light on,
what codes were present & did you diagnose
& repair them ?

Sounds like a bad fuel pump on the stalling or
no start

If the engine ran hot [overheated] long enough then there may be some internal engine damage such as a scored piston or damaged cylinder head. If the engine was hot enough when it was shut off or stalled it may have had to cool down for a while before it would restart. You might get lucky and the noise is being caused by something simpler such as a water pump bearing or drive belt pulley. I'd start by checking both the oil and coolant levels then inspecting the water pump and drive belt for any faults. If the noise is coming from inside the engine then you'll most likely need to have a service facility take a look at it to see where the noise is coming from. Good luck, hope this helps!

You might have a bad coil pack causing the engine to stall after it gets hot, I would start with changing the coil pack, good luck, Gary

check coolant temp sensor

you need to replace the coil packs.

If the engine stalling occur when the engine is hot the most probable cause is a vapor lock, this is when gas boils before it reach the engine, when the engine is extremely gets hot, the gas boils and an air bubble is formed which causes the air/fuel mixture to be too lean, too much air and not enough gasoline, thus making the engine to stall. When you experience vapor lock, just let the engine cools down, have a mechanic to check your cooling system it might cause the engine to get extremely hot.
