Have you gone through any troubleshooting already to resolve these crashes?
If not, you should try going through our crash help article linked below.
What do I do if ESO is crashing with the error "ESO has stopped working"?
Lools like the same thing happens to me. I've been getting frequent disconnetions for about a week.
It usually happens when I di. Just after coming back to life, I can't do anything but walk for maybe 1 minute and then I got the "Can't connect to servor, check your Internet connection" - which is fine, of course. I usually can reconnect immediately.
It also happened last night in the final fight with Montclair in Rivenspire. Suddendly, all mobs stood still and I could not attack them anymore or just barswap.
