Since they did work for a while, then quit, then work again, I'm pretty certain that the bulbs are okay.
I ordered another flasher and will try that.

Here's the funny thing.. The current flasher has a ground however it looks like it's tied into the two LED indicators in the dash and not to a ground. Since it was working, I'm thinking that it's setup correctly and will probably just connect the new one in the same fashion.
If that fails, I'm thinking about going with the toggle switch option..
