electrical trouble can any one help

I have a cherokee sport 2014 over the last month it has happened 4 times.

Car starts normally in the morning travels about 500 meters the as you go around the corner motor just cuts out. When you try and start it the motor won't turn over but sounds like the starter is trying to engage , sometimes won't start at all , other times waited a few minutes then tried and she starts bit like it's starting to flood but gets going. Other times had to jump start it.

Changed battery but still the same

has anyone got some clues
