Question about 2000 Jeep Grand Cherokee

Intermittent Stalling Problem Code: P1282

I have a 2000 jeep grand Cherokee Laredo, with a 4.7l V8 and I am having intermittent stalling problems. The jeep will run fine for as long as a week at times, and then all of a sudden it will start to die on me either while driving, or at idle. The engine will at first drop down to around 300-400rpm and get caught in a lull where no matter how much gas i try to give it, it will just sputter out and die. After attempting to start it multiple times after it will eventually start up as normal an be fine until the next time it dies. I had no engine light on, but turned the key over 3 times and got a P1282 code for the fuel pump relay control circuit. he fuel pump is brand new along with the relay itself. I just recently took the jeep into a shop and they tried running it many times over the course of a week but because it stalls randomly, it did not act up on them and they said they could not find the source of the problem. Any help or advice would be great, I'm not very good with electronics myself so I'd like to point a shop in the right direction and get it taken care of.

The Idle Air Control Valve (IAC) is a device that controls the air to fuel ratio in modern fuel systems. A long shaft, called a pintle extends and retracts on a spring within a housing to control the amount of air around the throttle plate. The Electronic Control Module (ECM) controls the pintle and adjusts it as the engine runs. Over time, the Idle Air Control module can collect gunk and get dirty causing the pintle to not extend all the way into the housing. This can cause the engine to run poorly and stall.
Cleaning the IAC
Despite what some will tell you, the Idle Air Control can be cleaned in many cases. It will have to be removed from the engine, but standard carburetor cleaner will often clear out the gunk and allow the pintle to slide freely again. Remove the unit, spray the cleaner into the housing and work a rag into the housing to clear out any remaining dirt and debris. Be sure to wear proper protective eye wear. You may need to let the unit soak in carburetor cleaner for a while. it may just be worth pricing it out before cleaning it some iac are very cheap like 20 bucks not sure how much it will run you. may not be your issue but you can at least inspect your iac. also you can pull out your pcv valve and give it a shake if it rattles your good also give it a visual inspection if it doesnt make noise replace it they are also very cheap

SOURCE: I have a 1999 Jeep Grand Cherokee. It was running

It could be a dirty idle air control valve located on the throttle body but when you said it backfires after running a while and before stalling, this sounds like a clogged catalytic converter. When blocked they will cause the exhaust manifold to glow red igniting gasses on the exhaust stroke, backfiring. A clogged cat will result in a loss of power as if you are trying to pull a trailer full of rocks uphill.
