so i was up in the snow tonight and i got stuck so i was trying to get out and i was useing the high rpms and then i got out and i heard a rod knocking so i put some oil in cuz it was really low and then i was driving it home trying to "baby it" and i was going up a hill and then my engine went boom and it shut off and it would start back up it seems like it is ceased up but not sure any thoughts on what it might be?
