No longer stuck in 2003
We need more details to help you here. First is it 4x4 or RWD? What engine is in it? What is the axle code from the door jam sticker?
Positrac is a GM version of a Limited Slip differential so technically you won't have positrack unless someone changed the rear end.
What exactly is the truck doing? Are you having issues going around corners? Is only one tire slipping when in poor traction or are both wheels slipping?

I have a 2003 RWD f150 reg cab, 113K miles, 5 spd manual. Today the rear end made a big "bang" when I left the driveway, shifting into 2nd. I put it in 'R' backed up a bit and limped back into driveway, about 100'. The left rear tire locked up the last few feet. I bought at an auction August 2016 and it's been fine. Any ideas.??

IF it locked up you probably broke a major part. It could be the driveline, or ujoint, but it could be a possible carrier pin, ring gear, pinion, something with the carrier/ring gear. Pull the rear cover and see how many pieces are in the oil, or if there is oil. You did say you bought it at an auction. You'll need the axle code, which is on the door sticker on the drivers side to see what you have. It shows the word axle and below it will be the code.
