2003 RX300 hard to start & stalls when low on fuel
Our RX300 is hard to start and then stalls whenever we let the fuel level get low (1/4 tank). This happens when the car sits for a while, overnight or a day at the office.
I thought it might be the fuel filter. Some posts have indicated the fuel filter is a lifetime part and stalling problems may be from a faulty check valve in the pump.

Next time engage the key and switch it to "on" or "run" ... detent before start. Leave it there for about 30sec to a minute and then try to start. In this position the fuel pump is supposed to prime-up and have the fuel available at the injectors.
Also tell us, once started.. how does it keep up with fuel demand when you drive?

Then it seems like a 'cold idle' problem and the fuel level in tank is a coincidence.
If you still think it is a fuel pump/delivery issue ... have a mechanic perform [do it with 1/4 tank condition that you mention]
a) Fuel pressure test. [this is NO flow just pressure]
b) Fuel flow test [this checks the volume/time]
Others can suggest test/remedy for 'cold idle'. These days it is all controlled by ecu and which gets input form sensors and the ecu sends the appropriate signal to the certain valves. lexus114 suggested the IACV.
