Jeep TJ stalling and rough idle

Jeep 1999 4.0L. Cutting out low idle/rough idle. Cuts out when at an intersection pretty much 100% if that intersection is on an incline/decline then struggles to start. When on motorway/highway runs fine. Normally starts up fine first time but if I then turn it off it will then struggle to start. This can be within 30 seconds of turning it off to 30 minutes. Seems to help if I pump the accelerator a few times. But then it starts roughly and sounds bad for a bit. There is fuel on the rail as I have pushed the Schrader valve thing and fuel comes out.

I have changed the IAC. MAPS, Throttle Position Sensor & the complete throttle body itself.
