Yes. It's been reported. Last time the cause was that the G-code contains the temperature specifications, so if you generate G-code, decide that the setting you had wasn't high enough, and try to print again without regenerating the g-code, you get this. The host warms the extruder to the spec'd tempurature, and then the gcode starts to print fine, until the temperature setting gcode is sent out and the nozzle cools down again.
Solution is simple: regenerate the g-code if you change the tempurature.
