All in the title i am at a BBQ. Sitting outside puffing away. I set it down for 5 minutes pick it back up and it isnt working. Managed to get it turned on and it just cycles through the settings on screen. NO1, NO2, Voltage, Wattage, Battery Level, Ohms. I can still vape it when i get it turned on but pretty sure its vaping at 3v/3w. Now im struggling just to turn it on. 
Any advice on what has caused this or how to fix it ?
