Zero tuirn mower will not move whemnngaged and moter dies

check and test the safety switches

Operator seat switch or connection failure

Sounds like you have a Relay that is hanging up

Sound like your using a zero turn mower. The brake must be in the off position for you to start moving. If the brake is on then it will die as you describe. Also a bad brake switch can do the same thing.

ck your occupant (seat) switch it might have gotten dislodged or unhooked when fueling it

sounds like the lowering moter has went out

Try turning the emergency brake off. If you move the arms in on my bad boy mower with the brake on the mower will die.

Check everything is clean. Check the air filter is clean, check that the engine cooling fan, cutting blades and cutting deck are free of grass. Check all the drive belt pulleys to ensure accumulated grass is not jamming anything. Check the fuel filler cap is clean and the breather hole works.

I have been told if the parking brake is engaged and you try to drive the mower it will instantly put a burn spot on the belt. I hope this helps.

The transmission is shot. A common problem. Mine died after 3 years and 200 hours of use. Estimate to fix was almost $2000. I scapped it and bought a better mower. There was a rtransmission design defect in the RZT series.
