Unhappy 2000 mustang GT (manual) shuts off, stalls while driving, please help!!

Hi guys i coulnd find no answer anywhere so i hope this helps.. You guys are the mustang geniusus!

Well started off like this i was driving like at around 2000 rpm and car just turns off on me? Idk what was wrong but it started up right after like nothing was wrong... Then started driving again.. After like 400 ft it happend again.. So i stopped for a while popped the hood saw nuthing was wrong.. Then started driving again, this time i jept driving like 5 miles then it happend again -___-

After months of this annoyance i drove it again.. Still the same.. But i notice it only turns off when the engine is at its normal temperature.. Not when cold.. (When its cold it drives like nothing is wrong)

Wgen it turns off it feels like if i just turned off with the ignition.. All the lights flash and stay on just likevwhen your about to fire up the engine.

Long story short:
-Car Turns off only when its warm
-randomly
-NO CHECK ENGINE LIGHT
-mechanic cant find problem :/
-checked fuses
-cleaned throttle body
-cleaned idle air control valve (iac)
-replaced some vacume lines

What i replaced so far:

-FUEL pump
-FUEL filter
-spark plugs
-crank shaft position sensor (ckp)
-throttle possition sensor (tps)
-camshaft possition sensor (cps)
-mass airflow sensor (maf)
-control module (CCRM)

Ugghh its so frustrating! I hope i can fix the problem and help out whoever is having the same problem...
Thanks guys!

So for anyone having this problem I think I solved it.. it hasn't turned off on me yet ever since

Heres what I did:
I cleaned the battery terminals the n regative connections that connects to chassy.. and the positive terminals.
&
Cleaned the egr valve n it stopped stalling while im driving..

I hope the car isnt messing with me tho..

A bad ground could be it. I suggest you check your battery voltage and check the alternator for a constant current while the engine is running, just to be on the safe side. A clogged EGR valve should not stall your engine, in theory. It should throw a code, or possibly make the engine idle roughly, not stall it. I'm glad you resolved it, and let's hope it doesn't happen again.

WAIT SCRATCH HOW I SAID I FOUND OUT THE PROBLEM!! I have found the real problem now.. iT WAS A BAD WORING HARNESS!!!! it has a short somewhere.. and it messed with the electronics and turned off my car.. I noticed the gauges does some type of MERCEDES effect.. all the needles would go all the way up and come back down.. so yea I started playing around with the wiring harness and the car starts acting jp.. I have to play with it a little so it dosent get that short anywhere.. ill try to post a video for yoyou guys cuz explaining in writing is pretty hard

mine did something similar to what you are describing, drove me crazy for a while. Check behind pass. Side kick panel previous owner of mine put a jet chip in and must have lost the bolt for it so decided to put zip ties around ecu to hold it together. After replacing the zip ties and taking the chip out haven't had any issues. I'm assuming that the zip ties and bouncing it was not a good connection at all times.

Hey I have the same problem with my 2000 gt, I haven't located any burnt wires yet. I've done so much but still can't figure out the problem. I seen a lot of different things about fords, but none really helpful. It sucks when your mechanic doesn't even know what's wrong.
