Hi, this is Russ,! I will give you the benefit of 28 years experience and teaching. If indeed the spark dies, then returns after it cools for a while, the solid state/coil is going bad. Replace the solid state or coil which ever it is equipped with. This is a rather common occurance in that it will "open" after it is used then "close" upon cooling. Thanks and good luck!
what is the color of the spark in the bottle of spark tester mine is some kind of orange thanks for your time

You should have blue, the orange is weak
Have a great day and if you need anything further, just address it to me, I will be in and out the rest of the weekend. GOD BLESS
