Second pack was good as well untill about 5 minutes into the run and it started stuttering BAD. I thought maybe the lipo cut-off was maybe coming on. So I hooked up the programer and made sure it was off. So to be safe I reset everything and re-did the radio setup. Ran another pack and it ran fine for the 5 minutes or so again. Dropped in another fresh pack to test and it started stuttering right away. Motor and esc has never gotten hot. Both have been only a tad warm to the touch. My setup is below. Am I missing something or what?

Car: Kyosho zx-5
Radio: Futaba 3pk with spektrum
Batts: 3700 GP, and IB 4200
Deans on the battery connection.
Motor hard wired with no bullets.
