My truck cranks and runs fine until it warms up then it will cut off when I stop

Idle air control valve stuck? When you first start up(cold) does it go to about 1100 rpms even briefly , or does it just hit 6-700 rpm's and stay there and gradually slow down when it's warming up.--coolant temp cool...injector pulse(fuel trim) is longer , when it warms up you get less fuel but same air maybe leaning it out to the point of stall.

Check engine light on? What is your automotive skill level? What engine? How many miles on odometer? Iac,Egr,Vacuum leak,coked throttle body Cts Iat Intake tube air cleaner. Many possible things.

I would check ignition timing.

Every time I fill up; completely full, it does this & on my daughters truck also. Don't ever completely fill your tank! My daughter thought it was the fuel pump; she replaced it and filter & when she filled up the next time it did it again.

had this problem. replaced egr valve and it fixed the issue of stalling out at stop signs.

Check your transmission fluid level make sure it's in ranges. It's common to stall and stop signs and stop lights if the fluid is low.
