It's a 05 putz 40z. Every morning when I put it pto the entire truck shuts off. I can start it back up but I have to leave it gear and pto I changed the parking brake pressure switches and checked grounds the next thing I was thinking is changing the pto switch it's self. Could that b the problem?

800 block prob maybe??

This sounds like a Ground problem. Have you checked ALL the grounds? there are several, look for one on the frame behind the grill Drivers side top of frame. Also at the Starter motor, also on the drivers side of the block as well as the frame on the drivers side by the shift tower.

Also check the output voltage for the Alternator, should be a Min of 13.6 VDC

I had before a similar problem in putz 2007 42 it doesnot pump and we found fault alarm then we found that the output volt for the alternator is less than the standard value
