Possible Electrical Issue??

So the other night I winched my buddy out of a pretty deep hole. Sounded like the winch was struggling a but but once I got him out, the speedo started going crazy then the outlander stalled out and died… It started right back up but the engine began to miss and speedo went crazy intermittently the way back to the truck and I could hear a miss in the engine every so often… And a couple times when I came to a stop it died again… This happen to anyone before? What could it be? The CEL is not on and there are no warning messages on the dash…
