fuel pump question?

At under a half tank at 70 MPH my check engine light came on and it started to run rough and lean.
Since my fuel gauge does not work I though I was running out of gas or the pump was dying.
It had started to whine the day before.
I did the key trick to pull a code of 34.
Topped off the tank and it ran fine.
Speed control Solenoid circuits is what code 34 is.
I thought it would have been a low fuel pressure maybe.
Any ideas?
I just had the codes pulled.
P0135 O2 Sensor Heater Circuit Malfunction (Bank 1 Sensor 1)
P0300 Random/Multiple Cylinder Misfire Detected
P0301 Cylinder 1 Misfire Detected
P0303 Cylinder 3 Misfire Detected
P0171 System too Lean (Bank 1)
It appears to be running fine now that the tank has been topped off.
