What prop are you running and what is actually frying? Pictures? How long are your runs?

Stock ESC should be good, you need to get 5.5mm bullet plugs between the ESC and Motor, that is the weak link usually, many times these come unsoldered, if you have temp gun, check it, will be surprised how hot the connection is!
BTW, if you want to up grade the ESC, my personal favorite is the Seaking ( Turnigy) 180A ESC. I have that in my MG with a Leopard 4082/2200kv motor running 4s2p.
