Angry 7.3 shutting off and irratic acceleration. can't figure it out

I have an early 1999 7.3 powerstroke auto trans
has an edge juice with attitude programmer

for the past couple of months my truck has been randomly shutting off while idling down the road such as when approaching a stop. I have replaced the map sensor, crank sensor, throttle position sensor, icp, and other pressure sensor on top of engine. it is still doing the same thing. it will also accelerate irratically with steady pressure on the throttle cruising down the road. what am I missing? is my tuner bad? help please

Ipr is new. That's the one I couldn't remember. Random searches are telling me cam sensor or bad connection somewhere. I tried running my tuner on stock. No change. I'm just wondering if even though its on stock setting the fact that its connected to almost every sensor is screwing me. That's my other reason for not takin it off yet. Its no easy task
