The engine has good vacuum. I have checked the check valve that snaps into the booster & it works fine. I'm fairly certain there are no vacuum leaks, and wouldn't think a vacuum leak would result in a random failure.
My question is whether a failed/ failing booster can do so randomly? Could 1 of the 2 diaphragms be bad?
I am happy to replace the booster, but hate to do so & find I have the same issue. It is the end of the season up here & it will be 5 or 6 months before I will know.
Anyone ever experienced something like this?
Thanks for any thoughts.

Hi Bill,
Did you ever get this figured out?
One customer was experiencing the same symptoms and turned out he was using a regular hose for the vac feed. Every so often it would suck closed.
