losing power after a few minutes

[Ecolandscaping17]

hey guys, need help.
losing power after mowing for a few minutes. hohler ech 749. changed coils, injectors, swapped clutches, battery is good and charging. compression is good. seems like it starts running on one cylinder but can't figure it out.

Could be an overheating ignition module or a bad ground somewhere causing the spark to drop on one cylinder after warming up, check all wiring and maybe try swapping the ignition module if possible, personally i hate heat related issue, they can be hard to track down sometimes

Did you check the fuel pump or fuel filter, maybe it's struggling to deliver enough fuel once it heats up?

Well it might be worth running it with the fuel cap loose if you want to rule out vapor lock. Heat can mess with more than just ignition.
