Probably ok then. Just to note, things made on these printers will usually not hold liquids. You can vapor finish them and they work better but will still have microscopic gaps and leak over time. They also promote bacterial growth due to these gaps. Just wanted to warn you in case you didn't know. There are limits to what can be printed.
On topic though it could be your power supply failing. Is the fan running? You should hear it ramp up when the extruder starts heating. If you around at about the 5 or 6 hour mark see how warm the air is coming from the vent below the power switch. If it seems really warm your power supply could be over heating and shutting down. During opration you should notice the fan is much louder than at idle. If not the fan could be bad which would overheat the power supply.
