When (1 of these):
1)An action is hapening: PvP (someone hit me), no more time to build, teleportation.
2)I stay a.f.k. without moving. (this is new)

The(1 of these):
1) minecraft is working for max 3 seconds but like there is not internet and next crash with error (Not Responding)
2) minecraft is working without crash but no one is moving, all is like blocked, like there is no net, with need of exit (Note: I have a very good connection, other games work)

Sometimes (not all time) hapen to tell me about Java(TM) Platform SE Binary is not responding, and tell me to restore or not.

Note: The console is giving NO information about crash, it work like no crash !

EDIT:

1) I do not know if is this the cause, but I found this as the last message:
