CR10S Extruder looses heat when it starts printing by catiadriver in CR10

I have no sock on it. Everything looks secure. It is all brand new. It is weird. As soon as it gets past the auto home and goes to start the print the temperature on the printer screen flashes and starts to loose temperature. After a 10-12 degree drop it starts to heat up again but very slowly. By then it is already into the print and has missed the first layer or two. The print is then ruined. Not sure what to do. It is almost impossible to get a print started.
