I'm at wits end and I can't afford to keep replacing parts.
I have a 2003 Suzuki DF140 4stroke with less than 80 hours on it. I was having problems with the engine bogging down when I tried to punch it.

Took it to an authorized Suzuki mechanic, in hopes of getting repairs done accurately. After spending $1,000 to replace Fuel Pumps, fuel filters and clean injectors, now I'm having a different problem.

If running the engine at 4K RPM or so, the RPM's start dropping to about 3600 and continues to jump back and forth. The engine does not stall and runs perfect at idle.

One thing I noticed is that every time the engine RPM's drop, the fuel needle indicates empty, then jumps back when the engine regains proper RPM's.

Does anyone have any suggestions? Ideas?
Please Help!!!
