Mossimo 500 efi utv stalls after startup loads up real bad. After it clears up it runs fine. Then kill it it might start but have to feather pedal. Fouls plug , Unhook injector, and fuel pump , replace plug, hit it with startin fluid till it starts. Plug all back in. Good for a bit. Cleaned 02 sensor, injector,map sensor, idle control valve, set valves, please tell me what I’m missing any and all help appreciated.

First post here hope it is in right place as I get familiar with sight. Have a 2003 550 mule,kaf-300-c7. Put on a new carburetor as old one was in bad shape, jet was frozen in body, although it cranked and idled fine. The problem is: it will crank and idle fine BUT with a slight movement of throttle it wants to die and when more throttle is given it picks up and runs fine. The old carb. and new one does the same thing. The adjustment with the plastic stop does no good. At a loss here. Could it be the fuel pump, as I know nothing about these kind of pumps. any help will be appreciated.
Hi everyone - I was driving my 2017 Cub Cadet Challenger 750 EPS today on the ranch when it dies on me. It started right up - and then as i was driving after about 50 feet the engine just turned off. It was running perfect before it cut out on me. No alarms, no weird sounds or smells. It just turned off.
When I turn the ignition key, the starter cranks away and the battery and starter turns fast and strong - but the engine doesn't start.
I've confirmed gas flow to the carb - that the fuel filters are clean and clear. I've replaced the spark plug with a brand new one. I checked every fuse with a meter. I have confirmed air filters and airflow are good.
But the darn thing cranks away without the engine even making a sputter or even attempting to fire.
Is there a kill switch somewhere that could have been tripped? I checked the seatbelt sensor, the brake sensor, and parking gear sensor - all are working and i'm in Park, pressing down on the brake, and have the seatbelt latched when i try to start. but - nada!
It acts like it isn't getting a spark. but like i said i put in a new spark plug. I have a feeling there is a sensor or an electrical kill switch somewhere that tripped.
open to any ideas.
