ANSWER: Sounds like a tired fuel pump.
If you have enough battery power to turn the motor over then I would guess fuel. Change your fuel filter to start and then if it still continues, measure your fuel psi at the schraeder valve. If its dropping or below 37.5 psi, its probably bad.
Fuel pumps over heat if you run the tank below 1/4 tank and then they start to die.

QUESTION: ok i have measured the fuel and it is steady at 41.5 psi even if the car seats durning the day it wont start only in the morning time like around 7.00 am and run like there is nothing wrong when the problem first started it gave me a code of po 306 (#6 misfire) the real problem i am have is i am loosing spark durning heat. wiether the car has been running or not in 2 days fuel is there the code reader telling me that both banks are not working cause of the o2 sensors all 4 of them are new but the fuel thing i have got psi of 41.5 at all times wether the car has ran for and hour or not in 2 days
AnswerOk so its not fuel It must be spark. Possibly something pulling timing. Disconnect the MAF and see if the car still stalls when the car gets hot. If it DOESN'T then we know its a sensor issue. Possibly the coolant temp sensor at the water pump is malfuntioning and pulling too much timing etc.
