This is because it constantly starts and stops the GPS and there is a memory leak bug in the GPS.end() function that is fixed with this commit: https://github.com/HelTecAutomation/CubeCell-Arduino/commit/85c0c7542b4496658624e578f45d187c321bc8ad

yes,GPS.begin -> serial-begin : malloc(buf),no free(buf),change to global variable or serial-end :free(buf)

In case anyone is still having this problem, in PlatformIO the solution is to change the platform in the platformio.ini file. If you choose the Cubecell GPS board when starting a project it will default to "platform = asrmicro650x". This platform is deprecated and must be manually changed to "platform = heltec-cubecell". Once this is done the GPS functionality will work correctly.
