C-12 cat issues

ok here's a rundown. I have a 2001 Peterbilt 379 with a c-12 cat( I know a baby motor but bare with me) 4 days ago it was running fine. Left tank says almost on E, right tank says closer to a quarter tank. I went to fire it up today because the weather has been very cold These last few days. In the low to mid 20s for the last 10 days. Could my fuel be frozen? But anyway It turned over but wouldn't catch. So I primed it 25 times and it almost caught but still didn't turn over. Eventually I turned it over and had some one push the primer while cranking and it fired up pushing blue smoke out the stack. It went up to about 9000 rpms for about 20 seconds then dropped down to 5-6000 rpms. I tried to push the fuel pedal to rev it back up, no response. I cut the cruise on and tried to bump up the rpms, no response just stayed at 5-6000 rpms. What could possibly be the culprit to this? I'm in dire need of advice. Thanks

 

Ok thanks a lot, will definitely keep that in mind. I'll try to fill it up tomorrow and see how it goes. I appreciate your quick response

 

Ok thanks a lot. I'll try that tomorrow as soon as I can. I'll definitely never let it run that low again.

 

Took the fuel filters off and they were like a sludge mixture. Put new fuel filters on, put Lucas fuel stabilizer and injector cleaner in the new filters. Dumped howes anti gel in the tank and it's been running fine ever since.

 

but truck and trailer is paid for so I'm happy with my C-12...and this is my 1st truck
