Default problems

I need some serious help here. My car was having trouble starting after a period of time sitting. The funny thing was it waould start fine after a few hours sitting. So i took to all my friends and we scanned it and couldnt find the problem. But by dumb luck i tested the battery and it was good until you put a load on it. So i replaced the battery and been firing up ever since. Until this past sunday morning when i left for a car show at a local mall !!!! So my question is what the hell is going on with my car?! I am going to test the battery tonight and see if its still good. If its not then i am thinking that i have an electrical short somewhere. If thats the case does anyone know if that is still covered under factory warranty? PLease help me, it sucks to leave for work and "HOPING" your car starts. Thanks for the help and suggestions

Seems to me like your altenater (not spelled right) is not working properly. Your car may be using too much from your battery.

if its your altenator, id recommend PA performance...i got their high torque starter and it even comes with a warranty and is 50 bucks less than the ford replacement...i think they got up to 200 amp

+1 on what he said or Duramax. Can't go wrong.... Have you tried using a tuner to find a code yet? Does your check engine light come on by anychance?

No my check engine light doesnt come on. I hooked it up to my friends computer and he didnt see any codes or anything. But he thought it maybe something to do with the car alarm, like shutting down some parts to the computer....

You got me clueless on that one.... I'm sticking to my Altenator theory.
