Why does my furnace work after power reset?

I’m having issues with my furnace sometimes not kicking on.
I hear the furnace start. But then it will not fire.
However, If I go down to the basement, and flip the power switch off and on, the furnace starts, and runs great.
It happens at least a few times a week.
Is the problem in the thermostat or the furnace? Where should I start troubleshooting?
It is an older Natural gas, forced air furnace but works great when it is working.
Installed in 1995 I think its a Honeywell

Your furnace controller board is very likely indicating a trouble situation and shutting itself down. This is the equivalent of a car turning on its check engine light and not wanting to move. Shutting the main power off clears the error code and allows it to work temporarily but doesn’t fix what’s actually at fault.
First, change out your furnace filter. Many error codes are simply because the homeowner never changed the filter. Check the manual to see if there’s a filter timer reset button.
If the shutdowns still happen then next time the furnace shuts down, don’t shut off the power. Take the cover off your furnace and look at the controller board. There should be a blinking LED. Count how many times and how quickly it is flashing. Reference your service manual to diagnose the code. You may have a faulty sensor, sticky motor, bad controller board, too many closed dampers, a blocked air return, incomplete combustion, cracked heat exchanger, blocked condensate line, etc etc. The blickenlights will tell you.
Ps. Since this is a gas furnace, make sure your carbon monoxide detectors are working and don’t continue to operate it in this unstable and potentially dangerous state. It could be leaking carbon monoxide into your home which leads to permanent nighty-nights.
