hey guys quick question...my 2001 accent 4dr will start up no problem when everything is cold, but once i let it idle for about ten to fifteen minutes and if i shut it off, it will start back up but then it stalls and wont start back up, or if i just let it run a little bit longer it also stalls, no problems with fuel pump or relay when it is cold it starts right up, but once it stalls it wont turn back on....the pump is getting power even when its hot so could it be a bad wire or should i test the coils when it gets hot or am i completely looking at the wrong thing?

i had the EXACT same problem on my 02 v6 sonata. it lasted 6 months, and was intermittent. turned out to be the coolant temperature sensor. i wasn't getting a check engine light or anything, but the sensor was faulty and would spike the temperature reading to well over 700 degrees, only for a second, which would stall the engine and keep it off. not saying it's exactly the fix you're looking for, but www.rockauto.com had them for 20 bucks shipped, def worth looking into. best of luck.

When you try to restart it can you hear the fuel pump running at the back of the car ?
If its not humming then I would guess pump or pump relay.

CPS or crank position sensor flaky will create no starts without a code. Cheap and easy to replace part.
