The problem is in the \score block.

I would simplify it to:

\score {
 \new DrumStaff = "P_PFour_Staff_One"
   \with {
     instrumentName = "Snare Drum 4"
     shortInstrumentName = "Sn. Dr."
   }
 \drummode { \P_PFour_Staff_One_Voice_One }
 % or you can write also:
 %\new DrumVoice { \P_PFour_Staff_One_Voice_One }

 \layout {
 }

 \midi {
   \tempo 4 = 90
 }
}
