That's because the caps, once discharged, are at 0 Volt and will pull any power the alternator provides during the jump start down.
The LiFePO4 battery should have its own BMS to protect it.

Hooking up a separate jumpstart pack will bring it back up, but as the caps can draw near infinite amperage it needs to have some kind of current limiter.
