If the PTO stays running when it stops, that would eliminate a mechanical clutch issue.

After that your getting into some complicated systems, I would suggest you get the WSM as it will have all the testing procedure.

Could be the hydraulic feed to the GST control, gear selector issue, or could be a internal failure or malfunction of a valve or part.

Be sure which model you have:
L5040 WSM P/N 9Y121-00052
L5040-3 WSM P/N 9Y111-03692

That unit has an independent PTO so if that and others are functioning I would suspect that the transmission clutch pack would have some weak piston sealing rings? Without pressure testing, this is pure speculation!
