2006 Mustang GT, stock, fuel pressure drop
regular maintenance on vehicle, 192K, 3rd fuel pump with same problem, all stock. happens more when the weather is hot. if I go on a big hill or mountain pass or if I accelerate to pass someone after 20-30 minutes of driving the fuel rail pressure drops and my car starts to stall. With each pump the problem comes up soon after warranty is over, I have a new fuel module, change the fuel filter with every other oil change between 6-7K miles.
