After a long day of mowing the mower was allowed to rest a while. My wife started it back up to mow a little more and every time you try to move it loses power and when you engage the blades it does the same. If you try to move it while the blades are engaged it'll almost cut off. This has been over a week now and I still haven't been able to figure it out. It runs normally unless you try to move or engage the blades.
