Nissan pathfinder 2005: car wont start when used for 10-20 minutes

(2005 Nissan Pathfinder)
When the car is cold it starts instantly and runs fine, however when the car is used for aprox 15-20 minutes it stalls a lot, the temperature is normal, however the relays are very hot, most have been replaced as well as the crankshaft sensor, camshaft sensor, fuel pump, temperature sensor, spark plugs, coolant sensor, plenumm gasket and was scanned and no codes was given, any help will be appreciated. The car runs very good, but when warm it doesnt start unless it cools a few minutes
What seems to make the problem better or worse? Worse when engine is warm
How long have you had this problem? Few weeks

My first thought is with fuel and air mixture ratios. If you do not have enough fuel pressure, when it is hot the fuel may vaporize before reaching the engine. If you do not have proper air in the intake - either too much or not enough -- the engine will not start. Testing is needed, instead of the replacement of parts.
