1999 Jeep won't stay running Sign In

I have a 4.7 v8 dohc in my 1999 Jeep Grand Cherokee Laredo. When we bought it, it was making noises, that we thought could be the timing. We bought the timing chain kit, the noise subsided. Then we had to change the cam sensor. Now when it starts it runs great, until it falls below 1000 rpms. After it shuts off it will not start, almost like it is flooded. We are at a loss of what to do. The timing has been checked 3 times. Can someone help?

Probably want to start off with pulling the codes and see if anything pops up.
To eliminate a vacuum leak I would (carefully) cover the throttle body with a rag or something while it was running & see if that would make it idle....
