Every 10/15 mins game starts to crash and lag.

Every 10/15 mins the game starts to lag and crash. I quit the game go back on it's fine for 10/15 mins. I've deleted and reinstalled, reset the Xbox, cleared cache. Everything. I recently downloaded mods and deleted them thinking it could be that, didn't work. I have a 1.8tb external storage device so it can't be storage. This has only happened over the past week and a bit. And only minecraft, it's happening on all other worlds.
