My husband has memory issues?

I have kind of a silly question in a way, but was wondering if anyone has ever experienced the same thing. Here is the story, my husband of 10 years has always had no problem with remembering things up until about a month ago. Several months back he started a new job working 16 hour days and we have struggled a bit with finance and raising four kids, so there is added stress. It seems like he forgets things almost instantly lately, for instance the other night he got off the couch to turn the light off and started talking to me and ended up sitting down without turning the light off (lol) and other things like that have been happening as well. Anyways the other night I was awoken to his loud snoring, this is nothing unusual he has always been a loud snorer and done it all ten years of marriage, but as I tried to fall back asleep I noticed that he would snore for a second then it almost seemed like he would hold his breath for 10-15 seconds before catching his breath and letting out a loud snore again. Almost like he was forgetting to breathe in his sleep. So now my question is, does anyone think the two are related? Do you think he is not getting enough oxygen at night and that could be causing him to have problems with remembering things? I have spoke to him about this and suggested he see a doctor, but my husband is a total GUY and will only see a doctor if it is life or death. If anyone has a similar story or some helpful information I could share with my husband I would certainly appreciate it. Thank you all in advance
