Thought about that but it doesn't do it on cold start. Once the engine warms up and I shut it off that is when I have the starting problem.

Check the individual injector resistances, I would expect you to see around 13-15ohms or slightly higher. If you find one or more that is significantly lower, you have shorted injectors. The resulting increase in current flow, is shutting down the injector driver in the ECM.
