JD 455 sudden engine stop.

[beenthere]

Not a sign of advance problem, fuel tank 3/4 full, mowing for about an hour and just suddenly the engine died.
No solenoid click when turning the key.
Will start checking if power at the fuel solenoid, as it does not react to the ignition key on.

Will track down if power at that solenoid, and report back.

Maybe it wanted a rest......

Check safety switches for build up debris.

The seat switch is jumper'd and don't think there is reverse safety switch on it. Was moving forward when the engine just shut down.
Will be able to check tonight if there is power to the shut-off solenoid. No activation of that solenoid when turning the key on. And the PTO switch is in off position.
tks for the thought of what to check.

I'll usually start by running through the fuses and connectors.

Browsing the tech manual, found test points and diagnostics, that I will attempt to follow.. maybe more floundering than following.

Did not get past the #15 or #16 test, so ordered the part #AM128878, control/fuse module.
Hope that solves the issue.

Reporting back.. that control/fuse module solved the problem. Easy install and back up and running again.
