toro 56170 starts and runs then stalls

[bruce728]

My toro 56170 starts and runs fine. After about 20 minutes it will just stop. I can restart in a few minutes later. Any ideas?

if its starts immediately after shutting down maybe a fuel cap issue if it will not start for several minutes it sounds like the module is starting to break down meaning when it gets hot it looses spark and after it cools down it will start again. if this is the case a replacement module should fix your problem
