Why does my hotspot stop after a period of time? I use the hotspot feature on my HTC One X alot for connecting to the internet with my laptop.  It's worked fine for months, but all of a sudden the last two days, the hotspot just stops for no reason that I can discern.  I have restarted my phone and haven't installed any news apps recently.  Any ideas?
You most likely have a hotspot timeout setting enabled.

You can disable it by going to your Advanced Hotspot Settings, and editing the timeout value to never.

Note that in some versions of Android in order to access the Advanced Hotspot Settings you need to first access the WiFi Hotspot Settings and then press the phone's Menu button.
