mtd 13aj775s059 shuts off when engaging blades but sometimes it engages and I mow for a while then it shuts off
 
It takes 3 things for a gasoline engine to run, air/fuel, spark, and compression. You will need to monitor the engine to see what is missing. Also make sure both cylinders are running when it is running. Sometimes when an engine is down on power it can be killed by load.

Motor is fine, it's when I engage the blades, also when Im mowing it shuts off, but when I disengage the blades it's runs
 
Seat switch will have a shorting so if the connector is it can cause intermittent problems. Otherwise here is a schematic to troubleshoot by.
