Unless you have heavy power consumers connected to the USB ports of the Pi, the power module should be able to run the Pi 24/7.
One common issue that I've heard about are undersized or improperly connected wires on the 12V input. 3A at 5V translates to about 1.25A at 12V. There can also be quick bursts of power consumption, especially while the Pi starts up, or does some heavy processing, which may cause sudden voltage drops with undersized and/or very long wiring.
I'd go with at least 24 AWG (~0.6mm diameter). Also use wire ferrules to ensure good and secure connection in the screw terminals.
