The "She Beast" is acting like all her filters are clogged. She'll run great for a short bit and then start surging really bad. The surging gets worse and the RPM's keep dropping (at max surge) till she just won't run at all . . . we wait for 5,10 mins and she starts . . . and off she goes . . .

. . . then it starts over again. I've changed the primary filter twice . . . getting to be an expert at that.
If you need to know how I can give you directions step by step ;)
