Have you had the fuel pressure checked?
A faulty fuel pump which builds-up internal resistance in its electrical circuits as it heats up can cause this, so the pressure needs to be taken when the engine is cool as well as when it heats up and the problems starts to occur. (This can be done by driving the vehicle with pressure gauge connected, that way you'll only have to raise the hood to see what the pressure is when the problem occurs.
Have you had the fuel filter changed?
A dirty filter can cause this and is a relatively cheap fix.
