replace the trans filter and fluid flush if that don't fix it the torque converter may be bad
first check the fluid level and for trans or trans line leaks

We had the same problem and found it was the fuel pressure regulator. Upon replacing it no longer gives any hesitation at startup.

I had a very similar problem except I would have to throttle my truck just to keep it running. It wouldn't even idle. If I were you check the spray pattern on your fuel injectors. It should look like a nice misty cone. Youy dont want lage drips of fuel, you want a mist. Also cut into your fuel line to test your fuel pressure. It should be around 9-13 psi. My truck had 3psi. I then replaced the fuel pump and the problem was solved. Hope this works for you.
