"[L]et off the gas...?"
What do you mean? Are you speaking about the hydro pedal?
Are you overloading the engine by pushing too hard on the hydro pedal? If so, increase throttle and decrease hydro pedal.
If the engine is shutting down as if you turned the key switch off when on steep side slopes and/or you are leaning to the side in the seat, tighten the seat belt and/or short out the seat switch.

Yes when I let off the pedal. Not overloading at all, just normal operation.
Thanks everyone, it sounds like it may be the seat sensor. Not sure I want to disable it (safety reasons on a steep mountain property) so I guess I'll deal w/ it for now...
I have the same problem with my B2650 cab model. I finally pulled the center cushion out of the seat and found out that the sensor switch is molded into the bottom of the cushion. I can be backing out of the barn, butt firmly planted on the seat, and it will die. I've had it die 4 times in a matter of 10 minutes, then run perfectly the rest of the time that day. Some days I don't have any issues, other days I feel like taking a hammer to it. :banghead: I feel like it, but I would never do it.
