Any heating and cooling Guys out there? I have a question

I have a Rheem Classic 90 Plus furnace.Here is the issues it kicks on and the pilot lights but then goes out.The pilot flame may go out after a few seconds ,or it will light right away and go out after a few minutes or several minutes.Sometines it takes 3 or 4 times before it lights up.Woke up yesterday and the house was 62,the wife was not happy...LOL I just hate electronic things.Had a electronic dryer and it mess up too.It seems the more simple things are the longer they last.


Thanks,Jim
