Check fuse 23 in the Power Distribution Center (PDC). This fuse feeds B+ from the Automatic Shut Down (ASD) relay to the O2 sensor heaters.

Yes if you have not it should be changed and you might look at the wiring to all of the 02 sensors to be sure they are not near the exhaust or rubbed through any ware.

if i replace the fuse and it does not blow should i replace the o2s or will they be ok
If you do not find a wiring problem one of the 02 sensor is probably blowing the fuse but you can try it and see if it blows again and if it does you will need to replace the 02 sensors.
