Engines idle for 15-20 seconds and dies
 
I did a swap 0n my 99 GJ 4.7 with a new motor, starsts right up and idles for 15-20 seconds then dies. I can't take it for a spin because it won't stay running. It will run if idles at 1000 or higher but when put in gear it pops and starve and won't accelerates at all. Put in park and then goes into to idle mode but dies after a few seconds. Anybody out there with any info would be greatly appriciated, All new parts were put in with the new engine but the PCM.

Quick response in the wrong area: You need to try to keep it running by keeping your foot on the gas. The CPU needs to relearn the parameters with it running, and you have had it go to sleep by disconnecting the battery.
