No hot water on main and 2nd floor -PLEASE HELP

Hi everyone I NEED IMMEDIATE HELP 🤬🤔

Approx 3 days ago while taking my early morning shower with water temp hot as normal (also stayed hot with prolonged use) the water went cold then got warm and fluctuated + - couple degrees never getting hot again. I checked all water faucets on 2nd and main floor and none of them get hot only warm. In my fully finished basement the water gets very hot as normal. Here are some details about my home:

-built 2002

-private well water

-Main and upstairs living quarters approx 3775 sqft.

-4 bedroom 2 full bath upstairs

-5 rooms + powder room on main floor

-finished basement is approm 1750 sqaure feet with 1 bedroom with full bath, 3 additional room + half bath.

-Maintenance room is unfinished with oil tank, air handler for main floor of house, and boiler/furnace (dont know difference) I will be posting pictures unit.

-I was told by a friend to check the units temp guage with no water running then with water running. Read slightly under 170 then had my wife turn on upstairs bathtub on full hot. Watched the guage drop relatively quick. Unit kicked on at 159 degrees and took approx 6 min to reach 180 degrees and shut off. The temp difference is set at 170 high and 150 low w/ 10 degree variance. I have a Beckett AFG model# EM-135 which is original from 2002. I hope I provided enough details (not like original lost post) for you professionals to give me some ideas on where to start looking. I am pretty handy so let's get into this! Pictures are attached. I appreciate any and all input and suggestions!! Thank you for your time and knowledge because this is one area I dont know anything about. If anyone needs particular pics please let me know and i will post.
