i'll appresiate any help!!!

Haha. A 2800kv motor for starters

.
I'm running a 1900kv with a 19T pinion on it and temps remain at optimal level.
17T on 2800kv -- Your ESC did exactly as it should. Burn out
To fix this buy a motor 2200kv or lower. I wouldn't run more than a 15 or 16T pinion with the 2200kv.
