I have a B&S V twin in a Toro ride on. Starts and run but occasionally after 30-60mins running it will sometimes loose power and will/would stall if I kept it loaded. Typically it recovers if left to stand for as little as 2-3 mins and might then be ok for another 30-60 mins.
First time it happened I thought the fuel tank air vent had become blocked but it's fine.
Replaced fuel filter, pump and vacuum hose as they aren't very expensive.
Today when it was misbehaving I noticed the engine wasn't running smoothly either when idling or running fast. It appears to run normal and slow alternating 2 seconds. Playing with the choke doesn't really make a difference so I'm beginning to think it's not fuel related.
Does this sound like a possible coil problem when hot?
Any idea how I might narrow down the fault before buying a pair of new coils?
