1998 Neon Engine Stall

I have a 1998 Neon and when it gets hot it dies and won't start back up
until it cools off, about a half hour or so, I can go about a mile and
it will stall right out, someone please help me.
I replaced the CAM shaft and the CRANK shaft sensors, but still the
same problem, tried to read the codes but no codes at all.
This is my son car wich he purchase 4 months ago, and it was running ok
till this problem started last week.
Please email me with some ideas where to look for the problem to



Thanks
