I have Taranis QX7 Modded with
- TBS crossfire small thing inside taranis
- Battery mod 18650

Sometimes can not power on,
Then i have to pull out and put back in battery, then it worked

Sometimes in mid air.. Have warning RX LOST for 1 second then connected again (transmitter is ON)

today I experience mid air RX Lost then fell down, I looked in my transmitter.. It is Off and can not turn back on.. Then I pull out and put in battery, it is ON..

Tried to check battery cable connection
Tried to change 18650 new battery
Problem still there

Really have no confidence flying knowing that connection is not secure

*by the way.. Another problem is sometimes sound is missing.. But it can be fixed guided by youtube tutorial.. And it happen many times

Anyone know how to fix this problem

Do you have this problem with Frsky SBUS or Crossfire? Or Both?
Did you have this problem before the TBS mod ?

Got this problem after TBS mod
And getting worse after 18650 battery mod

By the way..
18650 battery is 40A and 30 A

Is it too high ampere.?

Amp rating is maximum discharge. But the Taranis only draws what it needs and not more regardless of rating. So that isn't your problem. Likely something wacky with the mod that is causing your problem.
