M.2 drive doesn't show up on file explorer 45% of the time after start up. Any suggestions?

Okay I'm gonna start of saying I think I'm pretty decent when it comes to tech stuff or finding the solution and being able to fix it on my own but this one has stumped me. So I have 2 m.2 drive one that I put in when I made the pc and a second one when I seen a great deal I couldn't refuse. Long story short I popped it in the first time and did all the good stuff. I put a few games and softwares on it. Whenever I turn my pc on or wake it up from sleep there is about a 35% to 45% chance it won't detect the second m.2 on start up which makes me have to restart again to get it to appear. The first time it took a few tries to get it to appear but now it will appear the second time I turn it on just about every time. I can notice immediately at desktop since some short cuts will be a white page that are on that drive.
