I have had this truck for close to 12 days now and an having the following problems already

.
the truck will run for about 5 seconds and it Completely shuts down. My buddy out the esc in his same exact car and it ran fine so he told me it looks like the motor took a poop. Which really sucks because it's brand new bought from hobby shop here in Dayton ohio and the owner said once it leaves his store is out of his hands and there's nothing he can do. He don't even consider trying to help you. Now when the car stops it blinks real fat red blinking colors on the esc. But it don't rapidly blink on my buddies? Does anyone have any suggestions as to what's going on or what happened? Is never been even ran really motor is brand new. I hope somehow I can fix this or I just lost $350
please help me
