My wife's Nissan would not start so I jump started it and it started fine and ran fine until we put it in drive then it shut down again. There is no power not sure if it's the battery itself or the alternator. Any ideas or help is appreciated

 

See what the voltage is at the battery with the engine off, should be about 12v with a charged battery, and running, should be about 14v.

 

I will check that thank you

 

My bets r on the battery

 

yup prolly got a soft cell on 'er

 

Got it taken care of it was the battery which was less than a year old I got a new one under warranty.
