Unfortunately I’m not able to access my way working jungle queen, but I may be able to help. For issue #1, watch the coin unit as you press the replay button. It should move one step each time. Yours could be gummed up or the switch that limits you at 4 players could be getting opened. I recall having that problem on another 4 player Gottlieb where the spring loaded pawl that helps the unit increment was flipped back away from the gear so that it didn’t do anything. Hard to describe, but easy to see in person.

#2 is a stranger problem. I’d suspect a dirty switch or sticky relay if it needs to “cool off”. I just had a problem like that where a relay would stick when cold and then get going fine.

Good luck, you’ll get it sorted out.
