94' chev. k1500 stalling out and running crazy?

I bought this truck was told that it will run great for about a half hour but, then if you try to go somewhere from there it will stall out and And get this " the drive shaft locks up" wtf does this means. Im pretty mechanically incline but, have no clue what would cause this. Is the tranny shot? Temp doesn't show its overheating.

Just a shot in the dark.. Maybe the rear end? Check out the sensors MAF/O2 etc. I am assuming its fuel injected.
