Massimo MSU 700 Dies after 5 minutes

[Steve D 916]

I have a 2016 MSU 700 It starts right up, after maybe 5 minutes or so It dies. It is like something gets hot and shuts it down. I let it cool for 20 minutes and It will start right up again.  I was told it's the stater and someone else said it's the ICM. Anyone have this issue?

Do you have any kind of temp gauge? See how hot it's getting, and if the electric fan is coming on.

No , I don't think it gets hot enough for the fan to turn on before it dies

Check your oil level, check your fuel pump pressure and your ECU.  If the oil sensor is acting up then it will shut down the engine; also the stator and the pickup coil could be going out.

Check the valve adjustment, it’s a common problem with many of these engines. You may think this doesn’t make sense because you have done anything to change the clearances. It’s not uncommon to find the intake side with little to no clearance. Check the exhaust side as well.

Remove the gas cap and see if it starts right up.  If it does, your gas cap vent is plugged.  Air needs to get into the gas tank to replace the fuel that is consumed.

Excellent suggestion. I had a riding mower that would only run for several minutes, then die. It drove me nuts trying to locate the problem. But, after waiting for the engine to cool off sufficiently, it would start again. I finally drilled a small hole in the gas cap, and problem solved!

Just my two cents worth but I've seen ignition coils that stop working once they heat up.
