League Client Crashing 2 seconds into champ select.

I don't know why but from time to time i will be playing ranked games but my league client just crashes and closes but I'm still in champion select. The second i log back in, The queue would dodge and I'm forced to wait another 5 minutes to get queued up. It's really starting to cost me major LP and time and is starting to make question whether i should even play league anymore, Someone help me please.
