I have a DCK almost like yours except a year older with many other sensory issues.
A diagnosis seems difficult to obtain for his family. 
IMHO it is my responsibility to be on top of it. I need to help establish a potty routine for my DCK. My hope for him is that one day when the timer goes off, he will already be in the bathroom going potty ON HIS OWN. happyface It may never happen in my time with him (off to public school next year), but I keep that goal in my head for the days I am "over it"
.
Yes, it is frustrating and occasionally outright gross (raisin bran muffins anyone
) changing an almost 5YO.
Personally I'd take your DCB potty at 8:50 and every hour thereafter. I'd keep him in a diaper (no thin, leaking, rash causing, pull-ups) in between. I'd use the potty timer, set for 60 minutes, to alert me since he can't himself.
After a few weeks, reevaluate. Maybe move up to 90 or 120 minutes. I hope he will have much better progress... lovethis
