Possible low voltage condition would cause that kind of a problem. To small a cord without the ability to carry and maintain the voltage would cause a voltage drop. I would test the voltage supply and make sure it is within 10% of that required for your A/C to operate properly.

The compressor motor , once warm is grounding out due to wear and is going bad.Have the compressor replace while it is still clean is cheeper and easier that doing it after a burn out,which will eventually happen,if the compressor is tripping the brreaker as I suspect..

The problem is that when u add up the electrical draw from all of these appliances running full bore, your draw exceeds your available amperage. Now you are doing the math and saying no...... Let me tell you why. It is rare to find a situation where a 100 amp service actually porovides 100 amps. You almost always have voltage dropo. And when you are adding extension cords to the mix the drop is even more. That said, When you are using the AC try to minimize the use of other appliances, especially the microwave which is a big draw too.

moter or compresser pulling to many amps on start up you can purchase a hard start kit and also you can ohm out blower moter you could also have a direct short althoug not likly

If it tripps quickly you have a direct short which means a hot wire is going to ground. This can be caused by a wire that has melted and grounded, compressor burnt out, fan motor failure, capacitor shorted, or just one of the wires running from the above to each other. First try the unit with it just running the fan.. if it does not blw the breaker then turn it to a/c . If it blows the breaker on fan you have a wire probably shorted inside the selector/fan panel open it up and look for melted or burnt ends repair the wires if found wires slowly degrade and that creates heat which causes the wire to degrade more until something melts. If it only tripps when you put it on a/c then you need to ck the panel and then go on top and take the cover off look for damaged wires ect there is an access after you take the cover off to get at more wiring. Look for a capacitor it will be a silver or grey cannister with writing on it that says 5uf or 35uf and 200 to 500volts if it is 3 wire it will be the start capacitor for the fan and the compressor if not then you should have two capacitors on 5uf and one 35uf make sure the wires look good if bad replace wires and try the unit if not you will need to purchase a volt/ohm meter at a hardware store get a cheap 10 to 15 dollar one it will come with instructions or just ask the salesman. Then you will need to unhook the wires from the capacitor. 3 wire put ohm meter on ohms and place the wires from the center connection to the outside connection one side will be for the fan and one for the compressor. When you place the black on the center and the red on the outside connection and then reverse hold them for a few seconds the meter will drop and build up to 5 or 35uf then do the other side. The center connection is the same for both sides. If you have one or two two wire capacitors you ck them the same way just put your ohm meter leads on and them switch and see if it builds up try a couple times. If they ck bad replace it. If not then your fan motor or compressor are bad. Remember th capacitors store voltage and are hot even when the power is off you can short them by using a screw driver blade do not touch with your hand. You can check he compressor by grounding one of your ohm meter leads on the compressor scratch a silver spot for goodconnection then touch each of the 3 connections on the compressor if any of them show 0 ohms or close its shorted out. Always unhook power before handling the unit or testing for ohms. hope this helps
