At night and in the morning when the temperature outside is under 90 degrees, the AC seems to work perfectly fine. Cools and cycles appropriately. However, we are having a heat wave at the moment and the temps are over 100 degrees. Every day, between 2-4pm, when the temps are highest, the outside unit will simply shut off - fan and compressor. If it does come back on eventually, it will shut off again pretty quickly. The inside fan will stay on indefinitely since it will never reach the desired temperature. Once 7pm hits and temps go down some, it will come back on and work seemingly fine and everything will repeat the next day. Is this a sign that the compressor is overheating? Is the high pressure switch being triggered? All that said, the unit is 10 years old but never had any major problems with it. Thanks in advance.

First... Where do you live... City/State is fine... as we do not know the weather you are dealing with, without a location.
There are lots of things which can cause an AC system to do what you describe... IMO if you have not had your AC serviced in the last year or two... it would be a good idea to do so.
Some of the things that may be the cause of the cycling during the hot weather... could shorten the life of the outdoor unit.
Get a full service on it... you will be glad you did!

The information you provided is not enough to begin diagnose the problem.
BUT, we cannot give DIY advice. Therefore, the best advice is to suggest you call for a technician. He will examine all the system and determine the cause of the problem and recommend your options to resolve it.

Extreme weather stresses the systems. I would get a tech out to do a thorough service... be sure they inspect the inside as well as the outside. The problem is... there are many issues which overlap. One has to understand all of them... and work through them to gain the balance of the system working as it was designed to. Without understanding the 'big picture'... one is just taking blind stabs in the dark.
And yeah... the rule at this site is NO DIY... The owners of the site placed the rule in effect... those of us at the site abide by the rules...
There is, however, a 'find a contractor' page at this site... only the folks vetted to post as 'professional member' are allowed on that list... and only by their choice. Might look at it and call a few of them.
Hint: Do not take the cheapest one... rather the one that is the most willing to explain things. You will be glad you did!
