John Deere 4400 combine

[farmboypowerstr]

We use this combine once in a while so things don't freeze up on it, its in mint condition and like to keep it that way. 4x4 still works good also. Anyways the question is, once in a while the combine will just die, turn the key to start it, nothing, no lights or anything, just plain dead. Wait couple mins and it will start and run fine. Whats the problem with it?

Have you checked the pos cable going to the starter? Rats chewed off some of the casing and was shorting out. or the power wire going to the inj pump or it could be in the ignition switch.
Where do you live?

I checked all the other wires, so it must be the switch.

Thanks

Yea i would start with the switch

I would say the switch as well. Mine did the same thing two years ago. The way I verified it, was while the problem existed, I jumpered the two wires for the ignition circuit. Another thing though, just thinking, is the ignition circuit breaker. It is in the engine bay on the cab wall. There are a few there.
