Lt1000 stalls out after 20 minutes and when blades are engaged

My LT1000 stalls out after about 20 minutes. It runs ok then sputters and stalls. If I disengage the blades it will stop stalling and run. If I let it stop I can restart it and it will run ok for a few minutes. I have recently changed the sparkplug, fuel filter and airfilter. I believe this started after replacing the sparkplug (maybe). Any help would be appreciated!

Go back over everthing you did and just recheck it all, espically the connections on the spark plugs. Make sure the the boot or coil wire snaps on. Sounds to me like it is starving for fuel, does this have a fuel pump? What motor does your mower have?? Model number of engine would be helpful. If you say you put on a fuel filter could it be on backwards?? Or is it one of those TOP looking filters?? Good luck

The fuel filter is likely the problem. Some universal filters do not allow enough flow for a gravity feed system.

I replaced the new with the old one and had the same problem...could I bypass the filter temporarily to diagnose?

Also try checking the gas cap and see if the vent is open , the little hole sometimes gets plugged with little insects.

That was my next suggestion as well. Try loosening the cap next time it starts to die and see if it keeps running.

Like cheese said, there are some universal fuel filters that don't allow enough fuel flow. It wouldn't hurt to bypass the fuel filter and see if it runs then. If sounds like there is a fuel starvation because when you engage the PTO, it takes more fuel than just idling.
