Recently this has been happening.

I drive and all of a sudden the power slowly starts to shut off. Deck turns off randomly cluster light and everything else turns off then my engine would stop slowly. Then when I try to start up it wouldnt because of my battery. I changed the dizzy not too long ago thinking that would change and after I jump started my car it worked for like a good 3-4 hour then it did it again. I'm thinking it could be my battery or something else but I'm not too sure. Any ideas?

 

take the car in for a charging system test. check/clean your B+ and ground cable connections. transmission to chassis ground, and chassis to battery ground.

you can check the charging voltage with a dvom. but a more thorough charging system test should be performed by a shop

 

Sounds like you have a dead alternator.

its not charging the battery so your sucking all the juice out of the battery while driving

 

Oh yeah I forgot to mention that I also changed the alternator the same day I changed the dizzy. So im pretty sure I wouldn't be the factor. Had the battery tested after that and it said it was ok but I never got to bring it in for a charging test.

 

Is the alternator receiving volatage?
is there a belt on it?
Have you checked all fuses?

 

Yes and yes but I haven't checked the fuses yet so I should do that soon and hopefully that fixes the problem

 

check your grounds, bud. and make sure those terminals are clean and tight

 

$5 says the battery died after and drained your alternator. but that sounds like a alternator issue.

 

Do a load test on the battery. Should be 9.6 volts minimum with load applied.

Did you replace your alternator with an aftermarket one?

Aside from this, it could be that your ignition switch is going out.
