There are a few things that can disengage your pto. the Computer if working properly will disengage it if there is clutch pack slipage, your pto light will flash. Your supply voltage to your computer drops below 10.5v appox. When this is occuring what is your pto load ( heavy or light ) If you watch your pto speed in relation to engine rpm and see if both drop at the same rate if the pto slows and the engine doesn't, you have clutch pack troubles. The Auto III controler is a very good controler, not like the ones before auto I and auto II. Most likley not the computer. And check the grounds on the fire wall.
