I think i may have to separate problems, Im not sure. Occasionally the truck will have no power and i will have to jump it, but it only runs for about as long as i jumped it. I took the battery and alternator to autozone have they both tested fine. Next, the truck runs really rough, when i come to a stop the truck wants to stall and when it does it usually starts right back up but sometimes it doesnt and i jump it to start it again, and now just yesterday i started to see a little smoke coming from the right side of the engine and it smells like its over heating. Im not really sure on the mileage, i would have to go look.
