My keyboard stops working after 15+ minutes of TF2.

The past two times in a row i booted up and played Tf2, my keyboard controls stop working after a certain amount of time. However I am still able to press the F4 button in order to exit the game and enter the Dashboard (I use a 3.1ghz, late 2015 model, 21.5 inch screen iMac).

To elaborate, If i play TF2 for a long enough time, my keyboard controls (aside from F4) stops working all together. Yet my mouse functions properly. Also, when I make it to the dashboard from the game via F4, the keys start working again. So no, my keyboard is not dead, it's just that the key commands quit working after playing TF2 for an amount of time I am unable to specify due to me loosing track. However, when I boot up TF2 again, it functions normally until the keyboard commands stop working after playing it long enough.

In other words, the dysfunctionality of my keyboard is exclusively applicable to whenever I play TF2 for at least 10 or 15 minutes. So, is anyone of assistance?

It may be something related to the power, possibly you don't have enough of it for the keyboard to work properly ingame. For how much time has this been happening?

Have you tried a different keyboard to see if it makes a difference?

I'm not really an expert in computer specs, my friend had a similar problem once and it got fixed by time. Maybe you just have to wait. If it doesn't work just try to find someone to check what is the problem.
