Engine will not start without me pressing the gas pedal. After the engine does start, it will not continue to run unless I continue to hold the gas pedal down. After I drive it for a few miles, the problem seems to correct itself and it will idle normally. It never seems to idle rough - just normally or not at all. There are no lights illuminated on the dash and I have checked the fault codes and none are stored.

Start by checking the coolant temperature, throttle position /idle air control or speed control valveand MAP sensor-
The coolant temperature is operating in the normal range.
I replaced the Idle Air Control and that did not fix it, so I replaced the MAP sensor and that did not fix it.
I disconnected the battery in an attempt to "reset" the sensors. After I did that the truck ran fine for two weeks.
Only once since then has the truck stalled. Last weekend after a 20 min. drive down the interstate the truck stalled when I engaged the clutch on the exit ramp. As usual, the truck started up but would not run without me giving it gas when idling.
When I reached my destination, I let it sit over the weekend and when I tried to start it next it ran fine. That was three days ago and it continues to run fine.
If there is advice that can fix this intermittent problem I would appreciate it, if not I'll wait until it fails in a more permanent way...

Lets try the fuel presssure to find out what the fuel pump is doing and pressure regulator with and without vacuum applied before we head on over to the ignition system.
Suggested Repair
Test fuel pressure and the fuel pressure regulator with and without vacuum applied to see what the fuel pump is doing. If those checks are normal, move on to the ignition system. Coolant temperature was already normal, and replacing the idle air control and MAP sensor did not fix the intermittent no-idle condition.
Conversation Summary
A 2000 Dodge Ram 1500 5.2L will not start or idle unless the gas pedal is held, then idles normally after a few miles of driving. There is no rough idle, no dash lights, and no stored codes. Coolant temperature was normal; replacing the idle air control and MAP sensor did not help, and a battery disconnect only temporarily improved it. The expert recommends checking fuel pressure and the pressure regulator with and without vacuum before investigating the ignition system.
