I was just wondering why this problem consistently reoccurs? I'm sure it could be a few things but having knowledge of what those few things could be would be helpful.
Thank you in advance for your help!

It can be a bunch of things best thing here is get a compression check and leak down test on that cylinder see if it may be a something internal or maybe a bad valve seal. It may also be a leaky injector or maybe a bad plug wire
