I think I have it figured. I noticed that the harvest solenoid didn’t appear to be working from the get go, so it is relying on the hot gas to melt enough ice for the sheet to slide out under its own weight… the harvest relay is the closest component that could have been affected by tapping the loose rail back in. I also realized that the first sequence on start up is a harvest cycle. The unit did the same thing… ran for a few hours after it had time to dry out, then it would trip the breaker a few seconds after resetting the breaker. I disconnected the harvest solenoid, and it stopped tripping the breaker and I now have a full bin of ice. Next step is to replace the harvest solenoid, but pretty sure this was the issue. Working fine for now without the solenoid. Fixbear, I really appreciate your advice and suggestions!

Took me a week to get around to replacing the breaker, and I thought it had fixed the issue. The unit worked fine for about 6 hours, then started tripping the breaker again. It doesn't trip straight away, it takes a few seconds before it trips. Wondering if it worked ok after it was off for a week and dried out, then once there was moisture present again, something's shorting? Any thoughts?

SOLVED: I was just having the same issue and I found the issue. My Scotsman Prodigy CO330 stopped producing ice a few days ago. I was getting a Code 8, but also noticed a code 2 at times when I was trying to figure out what was happening, but always seemed to show a code 8 when it stopped. After cleaning everything, I noticed that the bottom horizontal plate on the evaporator was loose, and sitting out around 3/8″ from the others. Here's what I believe was happening… it would do a full freeze, but the protruding plate would prevent the sheet from dropping, so I'd get a flashing Code 2 (Max Harvest) and it would retry. The next cycle, because there was a sheet half way harvested already in there, it would run water over the sheet and the next cycle would trigger the thickness sensor early and give a code 8 (Short Freeze).

I found a hack online and used a hammer and flat head screwdriver to tap a cross into the joint between the loose horizontal plate and the first and last vertical plate. This locked the plate back in place, and the machine ran perfectly. I watched it go through 5 cycles after putting the covers back on.

I now have another issue… next day, the machine is tripping the GFCI breaker on the main panel. (I know, GFCI breakers are not recommended, but it's been running fine on this circuit for years). Every time I reset, it trips after a few seconds. It was working fine when I left in running the night before. I can't imagine that the run capacitor decided to randomly go bad right now, so I suspect I either pinched a wire somewhere, or some moisture from cleaning has got in somewhere it shouldn't have. Rechecking now, and will leave it off with the front and side panel off to see if letting it dry out help, but any other suggestions welcome.
