Some of the Coleman's used a time-delayed relay called a sequencer.
Clare's did too.
It could be on it's way out.
The schematic is on the panel that covers the wiring, right?
Change the sequencer.

There's the little peep-window that you can open to see the igniter ?
(its got a sight-glass on it)
If I leave that little window open, the sucker lights off !!!
WTF !?

That little window is for shipping only. Remove it for normal
operation. You may need to install a "lite-off@booster.
