MacBook Air randomly shuts off. I'VE TRIED EVERYTHING. Badly need help

So last week, I left my 2 year old Macbook Air on sleep mode and when I woke up in the morning, it won’t turn on. It had no water damage, i didn’t drop it either. I was trying to SMC reset the entire day and after a few hours, it eventually turned on. It worked fine for the next few days. Until yesterday, it suddenly turned off while i was in the middle of using it. I tried to turn it on again and it turned off again after a few minutes. At first it would turn off after every 15-45 mins, now it shuts down on start-up. It shuts down both when plugged in or even if it isn’t. I've tried every repair suggested on forums, but none of it has worked. I'd be so grateful if someone can help me

BATTERY HEALTH - I downloaded Coconut Battery to check my battery health. Full charge capacity was still at around 95% and i’m only at around 600 cycle count. Temp is just at 30 degrees celsius, so its not overheating. Battery status is good.

SMC RESET - I did a proper SMC reset. Fully charged it, properly shut it down and did SMC reset at start-up. It would still turn off after every couple of minutes but i continued to use it until it got completely discharged. Then fully charged it again. I followed a forum that suggested this, to complete power cycles. I've completed one power cycle, but the issue still persists and now it just shuts down at the log-in page so i can’t even discharge completely.

PRAM RESET - After SMC reset didn’t work, I tried PRAM reset. After i did this, it started playing the start-up chime again [which stopped happening when i was doing the SMC resets and the random on and off] and it worked fine for about 45 mins then it shut down again.

DISK UTILITY - Did scan, first aid repair, nothing wrong found.

SAFE MODE - Booted in safe and it still shut down after a few minutes.

APPLE HARDWARE TEST - Says no trouble found

I don’t know what else to do. I’m in the middle of writing my thesis so i desperately need my laptop. Id appreciate any help. Also wondering if I should just factory reset my Mac if nothing works? Thanks

UPDATE

I was losing hope today because its been 3 days, so i decided i was gonna try to just factory reset my system. Went to Mac Utilities to erase my disk. It just finished erasing my drive and then it suddenly turned off. When i turned it back on, it goes straight to internet recovery (so i’m assuming the disk erase worked) because the disk is now wiped and there’s no OS to boot from. Now even at internet recovery, usually around the part where i choose a network, IT’S STILL TURNING OFF.
