Hi David,
Some quick questions:
1) When you load your code on ECAP, did you make sure to update your required maps to the latest version of 10.0.0x? In other words, are you sure that while loading your project, you didn't bring old versions of our maps/apps.
2) When it "freeze", what's the status of the CPU? Is it kind of idle or burning at 100% usage?
3) How are you starting the image? As a Windows service or manually?
4) Is there a chance you run the image from a CMD, let the CMD open and when hungs, RDP into Windows and be able to do something?
BTW, since you have an active support license, feel free to continue this as a support case and we can assign engineering resources to it.
Best,
