Ok plot thickens! Warning buzzer almost never gos off when driving (with current issue). Today went off at stop light reached over to put cruise switch in off position to try and get code- switch cruise off warning buzzer went off? Trued to pull code - no code?

When pumps are ingaged rpm comes up to around 1050. That’s why oil pressure is up.

Oil pressure will read around 40psi. Temp level ok and at 185

1999 mr. warning buzzer go’s off then truck dies. Will start right back up. Usually happens when I’m out ok cab as it is a concrete pump and operated remotely. Did have buzzy go off on way hame Friday and raised rpm’s up and it went off. Tried to hold set button for cruise to get code but didn’t give one. Only happens at low rpm’s long as I don’t idea it down to far runs all day. Also hooked cheap scanner up and didn’t show any codes. May not give a code while pumps are engaged because control panel for pumps utilizes cruise control circuit for throttle.
