Need Advice in Scale Helicopters

Dear scale heli pilots,

Last week I was testing a new B212 build and got PHT2 (v12.79) cut-off after 5 min cool flight. The shutdown data is showing that the fuel pump voltage suddenly drop from 1.5 avg in flight to 0.9, then immediatly tried to recover with 2 volts, but too late; flameout. Hopefully no damage at all despite the crash looking impressive.

All other logged data like rpm, temp, turbine state, etc. looks fine. Also I couldn't see any bubble but maybe got expelled when the pump rushed to recover. The tank had about 30% kero left (felt clunk) but, as in doubt, I'm currently adding a UAT BVM.

My ask: I am correct assuming that the ECU does react to the presence of bubble or cavitation in the fuel line and is the pump expected to increase or reduce it's speed?
