In most cases this is caused by a dirty idle speed control valve, do the following procedure exactly as outlined and it should clear the problem after a few days of driving, I assume you have no check engine light or engine misfire and the car has been properly maintained.
Here is the common cause cold engine stalls, stalls at stops, slow idle speed, erratic idle speed, rough idle and engine hesitation (and other problems), it is in most cases the idle speed control air-bypass valve and or throttle valve and upper intake, these area's get full of gunk and combustion residue over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.

03 suzuki grand vitara starts up in morning after 10 minutes its warm drive to town shut off wont start back starts and dies starts and dies 3 times then starts and runs till next shut off


check whether you do have a problem with your cam or crank sensor. Or the fuel pump whether when it gets warm stop working,(loosing the pressure ) These things you do need a specialist to check the sensors and the fuel pump.

Engine cuts off when it gets warm have replaced fuel filter


You'll need to figure out if you are loosing spark or fuel pressure when it stops running.
I would say it is something electrical, could be anything from the ignition module to a relay.

My auto stop relay shuts off when warmed up, then lets truck start sfter sitting for a while.


You could replace it to cross it off the list. They are not expensive.
Or you could swap it out with another relay with the same configuration.
A mechanic would check the terminals when the truck will not start to see what is hot or not.

My truck back fires in the mrng why


check the engine coolant temp sensor. this sensor regulates fuel until the engine warms up. if the sensor is telling the ECM that the engine is warm on start up then it leans the fuel control out.

2001 Nissan Altima shuts off in hot weather


it is the cam position sensor...the telltale sign of the failure is that it happens when the vehicle is warm and has been driven for a while. Sensor is about 40 bucks at the auto parts store, make sure the replacement sensor is metal, not plastic.
The main symptoms of this sensor failing are rough starts, rough idling and not starting at all especially when warm.

Engine stops immediatly after starting


Sounds like faulty Crank position sensor. These tend to go out alot on Jeeps. Most of the time it will be running fine and then it will shut off like someone shut the key off. Hope this helps.
