The bolt loosens like every day leaving them loose as hell, and when I tightened them yesterday I went to crankflip and they spun fine until one spot and completely stopped. And once in a while they will skip a ton. My chain is really looose for some reason so maybe that is the skipping problem. What should I do?

Buy new cranks. But check your driver and bb too. Your cranks loosening isn't the reason they stop spinning when you do crank flips. Your chain being loose could be the reason it skips, but you could also have a worn chain/driver/sprocket.

Crank bolts usually only loosen themselves if something is bent, or the splines are worn.
