I had the same problem and found that quickly turning the key to start without a wait immediately after a failed start, would start the engine, but that's no fix.
A factory Allison facility replaced the TCM (Transmission Control Module) at no cost, since the tranny is warranted for 5 years. This fixed the problem.
Around the same time, another FR member had the same problem and fixed at an Oasis Freightliner facility. However, he had to pay because the Freightliner said they were not an Allison dealer.
