2000 Durango error codes

Last week while driving out of town we thought we had enugh gas to make it. We did however the low fuel light came on. After stoping to get gas, the check engine light came on. I hooked up my scan tool and got the following codes, p0171, p0133, and P1195. I attempted to rest the codes but they just come back. My gas mileage had been horrible sense. Any ideas?
