Issue #2 LS 3033H stumbles

[AUSTENNN10]

Ok I am into addressing issues today. Recently my 3033 with 60 hours on it stumbles (3 times so far) when releasing the hydro lever and starting to back up. (Just scooped up some dirt and now backing). I am almost or maybe I am doing both at the same time, and the engine just dies for a millisecond before it kicks back in. Checked fuel full, air cleaner clean, I got the tractor with the seat switch hot wired by the dealer and have not replaced the jumper so I think that's not the issue. I have not checked the fuel filter yet but will in a minute (no sure how yet). I seems electrical as its a really brief off then on but that's a swag.

Any guesses?

Thanks in advance.

Good question, I don't know but will check, I am a newbe and usually go by ear, ie does the engine sound overloaded or not. Also if we go down this path of logic I was switching between L and M as I was moving dirt and wonder if I was in M.
