snowbower wont stay running

I have a 2004 snapper snowblower with a Tecumseh 7 hp engine that wont stay running.i'll star it and it will run for about 4-6 minutes then stall. It will start right back up butnonly run for 3 seconds. i can do this several times. then it will run for the 4-6 minutes and then stall. i can do this routine several times and then finally it wont start at all. I have replaced the carburater and all fuel lines.

Wonder it it’s something with the ignition or a ground wire for the on/off that once it gets hot it craps out, once it cools back down I take it you can do it all over again?

Try loosing the gas cap, and see if it stays running. I would also check for spark, with the spark plug, although it sounds like it fires back up. Also the fuel line could be old and rotted, causing fuel starvation. Do you run it dry at the end of the season?

I had a Tecumseh 8 hp that did the same thing, It turned out to be a bad spark plug.

Crap in the floatbowl can also do this, and not uncommon from an old fuel line breaking down. Particles slowly get pulled into the orifices, and it dies, and after it is drug back, sloshed, sworn at, as well as elapsed time, will repeat. Other issues are more common, but definitely had this in a 7HP Tec 2 years ago. Had almost dustlike black crap intbe carb from the line,no matter how many times I cleaned it. One new fuel line, bowl clean, and tank rinse later, and perfect for 2 years!

Check your intake and exhaust valve clearance. The problem you are having is very common with either ignition coil not firing when it gets hot and also when the valve clearance is tight, and when they get hot, the stem expands and they will not close all the way to seal up the combustion chamber, causing lack of compression or "Spit-Back" through the intake system.
On the ignition coil, when they get hot, the windings in the coil expand and creates an "Open" in the coil windings, and No Spark.
Once everything cools down the coil might fire again and valves will seal again due to contraction.
Check those items if all else checks out ok.
