I was able to reproduce this issue:

git checkout 2.5.0
mftf generate:suite PaypalTestSuite

Actual behavior:

PHP Fatal error:  Uncaught Error: Class 'Magento\FunctionalTestingFramework\Console\MftfApplicationConfig' not found in /Users/treece/dev/mftf/magento2-functional-testing-framework/src/Magento/FunctionalTestingFramework/Console/GenerateSuiteCommand.php:52

Root cause:
GenerateSuiteCommand.php is missing:

use Magento\FunctionalTestingFramework\Config\MftfApplicationConfig;

Notes:
This is fixed in the develop branch already.

Workarounds:

1. Add use Magento\FunctionalTestingFramework\Config\MftfApplicationConfig; to the GenerateSuiteCommand.php file
2. Use generate:tests instead and then manually delete everything in the generated folder EXCEPT for the suite folder you want to run.

Fixed in the MFTF 2.5.1 tagged release that we cut earlier today. Thank you for your report @magicsunday!
