Well I was a dummy last week... I knew the fuel tank was getting low but I could still see a few inches of fuel in it (gauge doesn't work). I parked and shut it off facing up hill on a grade and it wouldn't go into gear when it first started up (trans pressure needle at zero). I figured I'd let it idle a minute or two thinking the trans just needed to circulate oil a little longer being that it was parked on a slope. Well then it started sputtering and died. Now I have to bleed the fuel system after I add some fuel. And then hopefully the trans will engage... I understand running out of fuel on the slope, but why wouldn't it go into gear? It's not a really steep slope so I wouldn't think it would be starving for oil. I've had it on similar slopes with no problems before, but only when it was already running, never starting it up on the slope.
