Sounds like a frustrated new owner. Not really here to get information as to what is wrong but just to vent. They really have not said what is happening. Is it as simple as way to much power use and the batteries just are drained? is there a display screen that is shutting off? When this happens what is the voltage remaining in the batteries? To many unknowns to really help out. So until then chalk it up as a vent and rant.
