Faze Foxclaw

Not sure on that myself, I am having issues, whenever I log onto SL I can only stay online for around 5-10mins sometimes alot less before it logs me off the game, can still see IMs etc despite what viewer i use, Other games working fine, Rift, WoW, Steam games. This is really winding me up been happenin for months really I jus get to the point where I give up trying again. But alas I wish to return to SL now!! hah Any ideas?
