About a strange error that made me think about the ranking system

After wining 6 rankeds in a row i had a strange error in seventh and lost it

1. game stoped after 60% on loading screen
2. i Loge off and restarted the game
3. after 2 minutes the game stoped(without "trying to reconect " )and this repeated for 3 times before the match was over(my network worked fine )

This isn't the first time i had a " game stop" out of nowhere after having (for me) unusualy good stats on ranked

now i wonder ,is there any in game "thing "(code) that decides who will be disconected or crashed after being very good in its division just because RIOT by some of its own hidden reasons wants him to stay in it(instead of geting higher)? What do you think about it?

i never had an error of such proportions, and i didn't have a serious error in-game for some long time (Firewall and antivirus are OFF during my "LOL-ing")

one more thing to clear things up....I am Bronze I on profile that i am writing about in text above and i do not think that i am some extra super player who deserves to be much higher on ranked than he is right now, but i like to know the truth.

This story looks pretty much egocentrict from my point of view but i decided to give it a try because,as i see it, there is too much of correspondences in a single situation (and it happened before)

Please help ...coment ...anything :)
