    Fuel pump/wiring issue?

    I am having an issue with a 2008 Tahoe, 5.3. Quit running Saturday. After sitting awhile cranked and ran fine. Quit again after driving about an hour. Fuel gage dropping to empty from 1/2 tank. Showed code p0230. Also, showing o2 sensor codes and blowing o2 sensor fuse. Any suggestions?
