Coolant spraying... What is going on?

I had a similar issue, come to find out it was because when the coolant started to get hot, the cap couldn't hold the pressure, so it just started spraying out of the overflow. Then when it cooled off, the bottle was low. New cap fixed it. Keep a spare under my bunk now.

started cold, hood was up, coolant just below max on the ProStar. Turn over engine, she fires, and coolant is raining down. First time, it was obviously coming out of the through the coolant cap on the bottle. Second time, it was hard to tell exactly, but still the same spray pattern and area. Thinking cap too.
