1995 T-250 shuts down at random times, now nothing at key switch or panels,,? HELP

[Deckerbob]

Hello forum
Recently, our 1995 T2 50 skid steer, would shut off at random times. After it shut off, I would turn the key off and restart and it will be fine. The rest of the day this would happen two or three times a day now I can't even get the bobcat to start or power up the panel. The battery is good. Oil levels are fine. I'm going to attempt to change out the key switch, which has a three wires molded into it white green and red, any help would be absolutely wonderful

I would check the wiring harnesses for any rub throughs or rodent damage.
Also, check your fuses and relays.

Are the fuses/relays under the seat?
I replaced the key switch, and still nothing… thank you so much for the help in advance

I swapped around similar relays still nothing, fuses are good… very frustrating…

I would be checking voltage to many things,a s sounds to me like you have a power flow issue, could be caused by a loose connection some place, or corrosion at a connection
so you need to be checking voltage at things and checking how clean connections are on as many places as you can

I'd be checking ground wire at battery and following it to see what it all looks like, poor ground can cause many issues
and on all older machines, corrosion is a big common problem, that green corrosion can get under insulation on wires too, so, if your finding it at all, it could be down stream under the wire insulation causing the issue, even though you cannot see it?
thus why using a volt meter comes into play!
also, when your taking apart connections checking things, its a good idea to be adding dielectric grease to things, to help prevent future issues

Thank you, I'll get on that right away

Do you have the deutz motor in your machine? Reason I'm asking my S250 did that to me every day. Until I found tge problem.
