my first guess it might be your fuel filter is clogging up and when it sits the crud drops down allowing some fuel to pass second guess your injectors might be clogging up try running an additive to clean them this would be cheaper to try first if none of that helps you might be looking at the fuel pump it might be heating up so no matter what you try it wont work until it cools a little just my guesses and past experiances lol good luck
