Murray 425620x92b runs for 5 minutes than dies won't restart until it cools. Than repeats again

do cold comp. test if below90psi remove muffler and inspect piston cyl. wall for scroing

check for spark when it dies you could have a bad coil

Check for oil filters on the wheel drives, Try replacing.

fuel pump i have a 1996 ford econoline and on hot days it will die and after it cools down it will run ur fuel pump is overheating i have not found a soulution to stop it from over heating

check for spark when it dies the coil might be failing

A number of reasons for this, poor quaility fuel causing vapour lock, over heating due to starter cover vents blocked,cylinder fins clogged, running too lean on the carb mixture settings, fuel tank breather clogged ( slacken off fuel cap when it starts to die, if it picks up again, replace tank breather, or ignition unit breaking down when hot ( only cure is to replace the unit )

You most likely need to replace the ignition module. You should find it under the shoud next to the flywheel, just follow the spark plug wire.

Replace the ignition module.

Sounds like your ignition coil is going bad.  I believe you can have those checked for free at your local auto parts store.  When they start to go bad they will fail on you when they get hot but once they cool down they are good to go again.  Let me know if you have any other questions.  Thank for rating my response and for using FixYa!
