sc10 brushless cutting out

[wheeliE-maxx]

I'm having a problem with my factory brushless sc10. It came stock with a 3300kv motor and an sc450 esc (link for reference http://67.199.85.166/main/productdet...ory=3400.escxx ) My batteries are older reedy x-rated 3300mah 6 cell matched packs. Under a high load situation, like full throttle from a dead stop with 100% traction it will cutout twice every time before it finally takes off. With any tire spin it takes off fine. Hot or just turned on, it does the same thing. The esc is set on the hardest hitting throttle profile. Any help would be appreciated
