It was running fine, but suddenly lost power (engine slowed)

Customer Question

It was running fine, but suddenly lost power (engine slowed) then died. Now, it will turn over fine, but will not start
JA: I'll do all I can to help. Tell me a bit more about what's going on so we can help you best.
Customer: That's about all I know
JA: Is there anything else important you think the Small Engine Technician should know?
Customer: It's a craftsman mower, about 10 years old. Nothing has replaced on the engine except plug
JA: OK. Got it. I'm sending you to a secure page on JustAnswer so you can place the $5 fully-refundable deposit now. While you're filling out that form, I'll tell the Small Engine Technician about your situation and then connect you two.

I tried to test the safety switch in the seat. There are 4 pins on it. I cannot find any closed circuit between any of them. All opens with switch depressed
Customer: replied 1 year ago.
Doesn't that mean switch is bad?
Expert:  Briggs-Fan replied 1 year ago.
Try locking the parking brake , that would over ride the seat switch
Customer: replied 1 year ago.
Parking brake locked. Put gas down air inlet. Still nothing
Expert:  Briggs-Fan replied 1 year ago.
Ok that's not good , check the oil , tell me if it's thin or smells like gas
Customer: replied 1 year ago.
Don't want to spend the $$. What's next?
Customer: replied 1 year ago.
No. Oil seems OK.

What's the easiest way to see if plug is getting spark? Can't get boot to slide up on ignition wire to watch for spark
Expert:  Briggs-Fan replied 1 year ago.
Remove the plug then hook the plug wire back up to it then ground the plug to the engine and turn it over to see if it's getting spark
Customer: replied 1 year ago.
It's getting spark. Plug looked fouled so I cleaned it up and put it back in. R engine tried to start momentarily, then backfired. Now back to just turning over..
Expert:  Briggs-Fan replied 1 year ago.
Check that oil and make sure it doesn't smell like gas or is thin
