It is mainly due to your internet connection. I suggest you to save the written articles in a notepad or word document before posting it in TSR. If any problem occurs while posting, you will have the original file.

You can also save in your drafts of TSR. Keeping backup of your documents is always safe. I suggest you to type first in your own PC using Microsoft word or notepad and then post in TSR. There will be no risk in doing so. Don't forget to save then and there. You might loss your data due to power cut too. I always type first in my PC and copy to the TSR. Think my information will help you.
