Hi, I'm having major issues with my Volvo. I replaced the battery and alternator because of the problems I am still having, thinking it would have solved this. My car is dead, I jump it and it runs for about 5 minutes, then it starts running hard all the gauges shut off, if I step on the gas to rev it nothing happens, the windows or anything power won't work, then it dies. If I try to restart it I need to jump it again, I have no idea what this could be. I'm assuming electrical, but I have no clue.....Any help would be appreciated.

 

Check out the V70 and 850 boards for a sticky on diagnosing battery issues. What happens with the voltage when you start up? You may have a current drain or even an ignition switch issue etc..
