So I took 2 pennies because I did not have any springs laying around put one at the spring and one at the positive contact. Now I can fire 30 watts all day no reset.. Obviously this is not a practical solution... So what should I order
Most likely it's the spring causing the issue. But you can get copper and brass plate from lowes in the hardware bins (probably Home Depot also) and make new contact plates. And I would look on amazon or similar for a beryllium copper spring or silver-coated beryllium copper spring that will work, you might be able to get away with just replacing the spring.
