CROWN SP 3500

I got a problem with a CROWN sp 3500 ac drive. As your driving the sp it will randomly slow down to a creep speed even though handle is twisted all the way forward. The platform is all the way lowered. No code , and then go back to normal speed a few seconds later while driving. I don't think its the pot because when its going slow, moving the handle doesn't effect travel. The truck will do this maybe twice a day, then go a month with no problems. Anyone have any ideas. Thanks.

sounds like one of the mast height switches is adjusted a little tooooooo close. might be a bad steering encoder.
