Weird Classic Woes - RAM or Logic Board?

I have a Classic that's being a little temperamental. It was recapped a while ago (circa 2018-2019) and has a RAM card installed. It's worked fine for most of its life save for the clock not taking when it starts up (not a battery issue...it just won't tick past whatever you set it at).

Recently, it's had issues where the computer will randomly freeze after about 2 hours powered on. It seems to do this when launching a program or putting something new into memory.

Classics have 1MB soldered to the board so I'm hoping those aren't the chips that are bad. I think I may have an extra RAM card sitting around so I could always try swapping that, but I'm wondering if there's something problematic here with anything else. I'm tempted to get a functional spare board, especially since this Classic is already BlueSCSI'd and a longtime favorite to put in the lab (one of those lighter weight computers with a small footprint that I can toss into the back seat if I need an extra one at an event).

Try to remove the ram expansion board and boot with 1MB onboard ram only, then run a memory test with snooper, see if it reports any error, although from my experience ram failure is always reported on boot up.

Will do. I'm trying to think of where I put my Snooper floppy now.

It doesn't Sad Mac at all, so I'm wondering if RAM is really the culprit or if it's something that's just an issue with the board itself.
