How soon long does it shut down for?
Does it come back if you turn off a/c for a minute or two and turn it back on?
Only on really hot days?
Only on hiway or also in stop and go traffic when hot?
When idling and parked is it draining water out the bottom as it should?

Do you have torque or forscan?

always comes back to cold when back to what seems to be almost engine idle speed or under 1500 rpm.. get up over 60km/h speed and anything other than light throttle and it is instant blowing warm.. you can smell the change in air coming then the warm hits you.. very frustrating! my 1997 f350 blows ice cold on low fan speed even in 33 celcius!! haha sorry about all the metric stuff
but if I lived in the hot states this car would kill you with interior temps.

went to the dealer again and of course idling in the driveway it blows cold.. he comes out with his little vent thermometer and says all is good.. I said get in and lets drive.. they would only do that on customer pay if no problem is found.. gotta a love the warranty/lack thereof.

love the car.. but since day one of ordering this thing and dealing with them and other shops is painful.

Get a new dealer, talk to the shop foreman and dealership manager. BURN them on the FMC satisfaction survey and tell Ford why.

Check your coolant level?  should be at full mark with engine cold/turned off and parked on level ground.  Wouldn't hurt to add an inch or two of the correct coolant even so, to see if the level goes down any and if the problem resolves.

They ran dye through the HVAC, and nothing was found?  Is it assumable that the refrigerant level is OK?  You can track AC status & pressures with Forscan, haven't checked with Torque.  I see refrigerant pressures around 600 kPa when off and up to 1700 kPa when on full blast.

Sometimes the AC pressure switch does fail.  Or the Schrader valve in the ports for the Hi and/or Lo sides gets stuck, so a fill/fill level indication is incorrect.

If tuned:  Take note of the strategy code as you return to stock (including 3 bar MAP to 2 bar MAP) -> take car in & get it serviced -> check strategy code when you get car back -> have tuner update your tune if the strategy code has changed -> reload tune -> ENJOY!

Newer cars are getting more sensitive to incorrect refrigerant levels and too much or too little can cause all sorts of cold air challenges.

If you have access to a set of gauges check the low and high side pressure in the system.

When parked I would see if it stops blowing cold when you hold the engine speed around d 2000rpm (above the 1500rpm where you have seen it stay cold.  If so you have a way of showing the tech what it is doing.

If you have Forscan or Forscan or know someone who does I would look at a/c high pressure sensor data (compressor shuts down if too high), engine temp (compressor shuts down if engine is too hot), a/c voltage (shows you what the compressor is getting to tell it to be engaged)
