How about posting some information on your specs. Are you on PC or PS3? If you are on PC what kind of hardware are you running.

I would assume you are on PC and your are crashing because you are at or below the minimum requirements to run the game. I've never had any of these issues you speak of. In fact for EA I was logged in 18 hours straight between two maintenance windows ran many many dungeons, story quests, cutscenes, etc not a single issue.

But I'm running a 4 core i5-2500k with an NVidia 760GTX and SSD hard drives with 16gb of ram on PC. Also my internet is a 30ms latency with a 50mbps download rate and I'm wired (not wifi).
