pack dies then comes back to life

[ak33]

This is everything I used
Losi xxx-4
Spektrum Radio
SMC 3300's (bought the pack used, looks pretty old)
Tekin G11 esc
Orion 11 turn

I used the pack for a good 3 minutes then stoped to try other tires, after about 1 min the pack slowed down and the car stoped moving. I picked the car up set it back down and it started running again for another minute then it died.

Any idea why it died then came back to life?
