MY 2003 Dodge Ram, hesitates when restarted and engine is warm. If I turn it off and restart it is fine.

You are experiencing what is called a CCD Bus short in the instrument cluster circuit board. (chrysler calls it the "chrysler collision detection buss) it is how all of the controllers and modules communicate on that vehicle. Get a new one and you should have no problems, and used ones are a HUGE gamble. Other vehicles that are extremely bad for this are, caravans, neons, sebring coupe/conv, strates, and cirrus. It will also cause a no start condition that is EXTREMELY hard to catch.

most likely problem is the crank sensor. they are bad about not wanting to work after they get hot, which explains why it works after a cool down. they usually won't set codes in that situation. but if you have a check engine light you should get it scanned first. auto zone will do it for free.
