No power

[TheNooB]

So recently my s14 lost all power (between the time i left for work in the morning and the time i got back to my car about 10 hours later) and then after about 15 mins of trying to start it, it came back and the car was working fine. Then two days later, I drove it around a little bit turned it off and about 15 mins after that no power again i had to tow home 5 hours after power was lost.(Clock was only thing working when car had no power and it kept resetting to 1:00 every time i took the key out and tried to start it again) Also, when i turn the key from the 1/3 position to 2/3 or 3/3 the clock comes off too. Now two days later i went and bout some new fuses and an ignition relay and changed most of the fuses i thought where possibly part of the problem (eng, alt, batt and a few others) now the car works fine again but i don't know if it was because of the fuse change or because i left time pass again... I also need to install a new starter i dont know if that changes anything. please also let me know if i even need the ign relay. Can anyone help me out i need to fix this asap!!!!!! i dont know how the answers are seen on here but email [email protected] if it doesnt send an answer notification.... THANKS IN ADVANCE
