Problems with brand new gx cs2

Hello, first time posting but long time lurker. I have a question about a gx cs2 pump I just received (I have reached out to support on social media and email but I get no reply).

I tried the dead head test, the pump reached 1500 psi in 35 seconds. I tried again and it wouldn’t get above 1000 psi. I then made a mixture of water and dish soap, and went to try and find any leaks. Now when I turn the pump on and tighten the pressure release valve all the fans stop running and the pump will slow to a stop. Once the pressure valve is opened, the fans all come on and compressor will kick back on. I can’t even get to 1000 psi anymore . Any help would be appreciated.
 
Thank you for the ideas, once I am home from work I will check on the outlet amperage. I was plugged right into the outlet, no extension cords. The first two dead head tests I ran, everything worked fine (fans and compressor), just wouldn’t build pressure. The third time is when the fans and compressor stopped. Thanks so much for the help!
Mike
