What spur and pinion are you running? More so the pinion gear.
 
id go brushless on this but Id say its going to last much longer than Any brushed motor . but you would have to go with a combo esc/motor combo..
 
I would put in a brushless system like others have mentioned. Running a pinion too big will definitely heat up the motor but brushed motors don't last long unless they are in a crawler.
 
There are a few reasons the motor may be overheating. There may be something binding. Too tight of a gear mesh with the pinion and spur. I think the stock Latrax has bushings not bearings. Before you go brushless you may want to install bearings. Any parasitic draw such as unnecessary isn't going to do a brushless motor any good either. The car will be a little faster with bearings anyway. Brushed motors will last but just like any electronic component heat will kill it. Bad connections will cause excessive heat also.
