But you probably already know that. Has a service tech actually driven your coach?

Yes, I know what turbo lag is. But what I am experiencing is that the engine just shuts down completely, like turning the key off. It usually startles me and I lift off the accelerator. Press the accelerator again and away we go. Never missing a beat going down the road. Have tried to be ready for it to happen and not lift from the accelerator, but it always catches me off guard. Like I said previously, it's possible it may be the transmission not downshifting back into first gear before the stop and that it is trying to get into a lower gear when starting off and it goes into a false neutral. It has no consistency to when it may happen. Did it the first time on way home the day we purchased it. Did it yesterday on a short(45 minutes) test drive after being parked for a few months.
And yes, it has been driven by a Spartan factory tech and Cummings tech.
Their quote, "Cannot duplicate the complaint"
Being a mechanic myself, I can understand. Wouldn't expect them to take it out for 2-3 day drive just trying to get it to repeat the issue.
Was hoping maybe someone possibly has had the same issue.
