groundman,

Sounds like the battery is not fully charged. What you describe is exactly what happens when you hit Low Voltage Cutoff (LVC).

+1, Try another battery that you know is good. if you have pulled that battery down that low it is more than likely no good anymore.

Sounds more like the BEC is getting hot -then cooling
Very common failing on electric powered models where the power battery feeds power (reduced to aprox 5.5 volts) through the BEC to the rx
cause - too much power being pulled by servos ,is typical.
The BECs are the weak link in all these setups.
The stronger the power battery and the more power pulled by the motor - the worse the situation will become because the ESC heats more .
