Think I resolved the issue. Battery cables had become a bit loose. Snugged them up and no problems since.
Battery cables don't usually come loose. You might want to add that to your maintenance list.
Id be curious still about the trouble shooting steps should the issue crop up again and it isn't the cables.
I check things in this order...
• Check any fuses first
• The seat switch gets more 'action' than any other switch, so check that next.
• Then check battery and battery connections at BOTH ends of BOTH cables. The Negative cable should be tied to the engine housing, not the steel frame of the mower. Expect problems if the larger cable terminates on a rusty frame.
• Then start troubleshooting the starter circuit.
► A dead battery could be unable to accept a charge OR a battery that is receiving no/low charge. The best test for a battery is a
"Load Test" after being charged for several hours. Any auto parts store can do a
Load Test.
► Motorcycle and car wiring is protected from rain and wash water... mowers not so much. The more you wash your mower, the more you should expect electrical connection and electrical switch issues due to corrosion on the contacts. It is best to treat electrical terminals with an anti-corrosion electrical compound any time you disconnect something to replace or do a test. Such a compound is

Hope this helps.
