I have an MTD 139cc lawn mower, model # 11A-54MB029, and engine model # is 1P65M0. It died and did not start again after hitting a stump. I re-gapped the ignition module, I adjusted the valve clearance which were off (.004 intake, .006 exhaust), and put on a new plug. The flywheel and key are both intact without issue. It fires up first pull now. It runs strong, then 15-20 seconds in, it starts dying slowly, and RPM's drop significantly. I can hold the governor, and it will run and even out. Any ideas what it could be? Weak coil? Governor messed up?
