Laptop has some sort of adware

Here is an idea.
It sort of sounds like there is a blockage after a while in the gas tank.
If there were sediment in the bottom of the gas tank, it would start and run fine sitting still.
However, when driving it, it would be a matter of a few minutes until the sloshing of the fuel would cause the sediment to mix in with the fuel, and clog the filter screen in the fuel tank.
When it stops, the sediment would settle back down, and in 15 - 20 minutes, it would be clear again.
God bless your efforts.

Read entire posting before doing anything else first.
I discovered what the problem was, after changing spark plugs, fuel filter and air filter (At this point the mower would not start at all):
1. Checking for spark. I got spark out of both plug wires. The modules were OK.
2. Checking for fuel flow. Only small amount of fuel coming out of fuel pump. I changed the fuel pump. (I bought a Briggs and Stratton for $22.50 instead of a Kohler for $60.00. Same fuel filter!)
It ran fine for 10 min. then quit again!
I loosened the gas cap and it has ran fine since then, by keeping the gas cap loose. I will replace the gas cap.
Note: It was difficult to find the problem, since I replaced the filter and removed the vapor lock, so it ran for awhile. I then checked the fuel pump and removed the vapor lock, so it ran for awhile. I would suggest that people with similar problems, loosen the gas cap to see if that works first!

Bent valves- my 96 civic had that too. it's a manufacturing fault. Have you mechanic do a leak down test.

Have you got any adware protection something like spybot search and destroy or antivirus software with adware protection sounds like it could be adware.

This could be that the battery is slow. Newer swiss watches have a indicator in the movement of the watch that makes the sweep second hand skip every few seconds to indicate that the battery is slow. On regular japan made watches the watch just simply starts slowing down. Your watch could be new but the battery in it could have a long shelf life.

drain the oil(all of it) and put on a new filter.sounds to me like you are missing a gasket to the crank case.

check the engine ground strap

Nortons only protects you now, It will not fix a previous problem without sending them more money, try running Ad-Aware from Lavasoft it is free, and also download and run CCleaner they both are free and clean-up registry problems and adware plus much more.
