Karlotta's car is very weak

Description: I recently bought two tripods so i could have still cameras while driving, i had to go to a friend's house so i decided to do it on the fiat uno, it is getting weak, it turned off several times and i didn't want to turn it on all at once, i did. the last one i had to get out of the car and leave it there so i could call for help since it never started.
