Just a thought but have you ever replaced the fuel lines they may be getting weak and maybe the heat softens thems enough the collapse while its running and when you let it cool it runs again??

I have not replaced the lines yet, but it is probably one of my next steps. The lines should be cheap and fairly easy to replace.
The thing is that It was hot out the day that it stalled and was just as hot outside an hour afterwards when it started up just fine, and it ran it for about an hour and a half with absolutely no hint of an issue. I shut it off and went to restart and it had the issue. The issue was that it was running rough after I turned off the choke. By rough I mean that it would rev up and down very rythmically rather than having a constant RPM. From past experience I know that it would have had very little power (IE woudl stall under load) unless I moved it to full choke.
I am also considering swapping out the fuel filter even though it was replaced less than 5 or 6 runnning hours ago.
It is supposed to be cooler this weekend and would be a good time to check if it is outside temperature related, but I don't have any tractor chores to do.
I'll run it a little a few times to see what happens.
Come to think of it when mt gt242 was new it did that and they adjusted the float I belive and I have not had a problem since..It kinda sounded like someone was moving the throttle up and down real fast and was hard to start!!

I had the same problem a couple years ago. On the left side of the motor, just in front of the fuel filter is a rubber line; I think it is an air intake (I could be wrong). Anyway, with my son starting the tractor and keeping it choked, I covered the hose with my thumb. In about 3 seconds, the engine ran fine. I changed the filter and all has been good on that front.

I ran it for about 45 minutes this wekend with absolutely no hint of the problem that I was having. That being the pulsing rev up and down.
955er,
By the same problem do you mean not being able to start it? Also, what filter did you change? Air or fuel?

I replaced the fuel filter, the one with the resevoir. It can look clean, but holds a lot of gunk. When I covered the hose, it blew a clog. It always seemed to occur when I had been mowing for over an hour, and when the fuel tank had less than 1/8 of a tank.
I really believe you have a fuel filter/line issue. I bought my 275 in 1995 and have never adjusted the carb. And I have worked it hard.

Still sound just like the problem I had with my 345 20HP Kawi. After 2 years of futzing around, rebuild fuel pump, carb, new filters, solenoid replaced, shut-off timer replaced ... turned out to be the ignition module ($220 as previously stated). Sometimes fuel and electrical are hard to diag. I also had the no fuel symptoms. But after plugging in the new module all was well. It CAN be really annoying especially when I was plowing snow and it would die after 15 minutes, then I'd wait for an hour and it would restart. Good luck.
Help!! I also have a JD GT275 which I have starting problems with. It ran well last year but not now. Initially it would start but as soon as I tried to move it would die. sometimes I was able to creep slowly forward at low speeds. I suspected a fuel problem so I done the following
1) cleaned out the tank ( there was som crud in it, 2) new fuel, 3) replaced all the fuel lines, 4) new filter 5)cleaned out the bowl at the bottom of the carb. 6) blew out the carb.
While doing this i notice the carb bowl float initally was a little sticky but after a few cycle it seem to move free. The gas shut off solonoid/pin does not retact on its own when power applied , if depressed it does hold the pin down...is this normal. I saw somewhere a person cut the pin off in lieu of replacing it ???
After putting it all back together it is not running any better... with the throtle full it start but dies after 10-15 sec Something I can get to run a little longer by reducing the throttle to slow.
ANY Ideas???? I really cant afford to take it to a dealer

Will it run under load if the choke is on?
