Starts and runs when cold after it warms up to running temperature about fifteen to twenty minutes it stalls and and will not start again until engine cools.

You are describing the typical symptom of a failing crankshaft position sensor or camshaft position sensor. They often fail by becoming heat-sensitive, then they work again after they cool down for about an hour. A good place to start is by having the diagnostic fault codes read and recorded. The people at many auto parts stores will do that for you for free.
