I have no idea what this car looks like but then iam in europe so what else do you expect but this problem i have come across often but mainly with older the vehicles with a ignition module not a later one with a coil pack but when i have had later cars like this then it could be a autochoke temperature sensor ,The problem is your working in the dark and spending a fortune on parts and to be honest you will need to concede defeat and take it to a dealer who has the correct software to read the ECU and see whats happening ,even newer cars especially renaults have to be connected via the internet to do this so no dodgy mechanic in a dealers can copy the software and flog it on the black market or E bay.So best advice i can offer is to take it to the dealer and swallow your pride and pray to whatever that a 548 chevy or a ford cortina comes on the market with no fancy electronics,how do you think i feel giving advice like this after 40+years fixing motors and new ones i cannot even change the brake pads as its dealer only job via the internet with the bar code from the original packet of manufacturers pads or the immobilisor isnt released and the ABS .6 years at college as well and reduced to a semi skilled drone

You may need to check fuel pressure after the engine warms up and shuts off. Maybe the fuel pump gets hot and stops. Have you checked for spark after it dies?

Engine coolant Temperature gauge fluctuates

Watch the temp gauge when the electric radiator fans come on. The temp sensor that controls when the fan comes on may be faulty.

Motor shuts down when reaching normal operation temp

Sounds like the mass air flow sensor or the air intake temperature sensor. Sometimes just wiping out the throttle body/air intake can make all the difference

AC stops working when cabin temp reaches 109-110

indicates gas pressure and condenser cooling problems
check the condenser fan is working properly and have the gas pressures checked by gauges
check that the evaporator fins are clean and not blocked as ice build up will cause the same indications
