May be a semantics issue going on here and this may be way out in left field. TW (Totally Wicked) Attys are most likely rebranded Joyes, but who really knows coming from Chinia. They are NOT dual coil. They have been a reliable atty with a very good lifespan in my experience if kept wet. I know I have several that are pushing three, yes 3 months old with little or no maintenance.
PS. Is there a dual coil atty on the market now ?

Is the titan actually the joye 510, so it's a dual coil? If thats so, then I think I know what happens when after a few days of vaping it suddenly keeps shutting off.
When I read what you said, I tried cranking the voltage on the VV way down, and when I got to around 3.7v it started working again. Makes sense if one coil died then the resistance dropped as well. Basically using a LR atty now, not the best thing to use on a VV mod
Sound right?
(I broke my cheapo multimeter the other day and my Mom is sending my good one down from storage and I should get it tomorrow.... sucks not having a DMM).
I would be surprised if it even produces much vapor. A 3 ohm atty will give you 8.3 watts which seems to be a popular sweetspot. Actually, somewhere between 8 to 10. 
just remembered you won the 5V. Yeah, try a 3 ohm atty.
i think that would eliminate the only thing i've seen that's a minus so far. my voltage will drop a few points from were i set it ( if i have it real high) unless the battery is fully charged.
