Alright, here we go. my trucks an 04 1500 hemi. Recently i went to start my truck, and as soon as i turn it over, all electronics in my truck just shutoff and kinda pulsate on and off including my dome lights. we pop the hood and tried to turn it over and jump it and all we heard was a buzzing coming from the fuse box, so we took it off and narrowed it down to the fuel pump relay. Tried switching it with another one in fuse box and it did nothing. so i called triple A just to get it towed home so i can check it out when i got home. After an hour of waiting, he gets there, hooks up the jumper box and it fires right up (I have no idea what happened lol) and everything worked fine for about 5 minutes. i put it in reverse, backed up and started driving forward for about 30 feet and feel complete loss of power to the pedal, so i throw it in park and rev it to make sure im not losing my mind and it revs just fine, put it back in drive and it drops to about 300 RPMS and eventually dies. so i had him tow it home s i can check it out in the morning. went out the next day and started it up cold and put it in gear and it dies again. Started it up again and let it idle for about 10 minutes and went back out there, put it in drive and it runs normal again like nothings wrong. I know this is alot to read lol but any ideas what could be going on? any advice would be great. Thanks!

How old is the battery?

 

Battery was replaced last winter. i checked it out and there was some corrosion on the cable so i cleaned it off and reseated it and it still was acting up...

 

All the charging system connections good? Including starter and alternator? Check all your grounds as well.
