When a riding lawn mower squeaks and stops when you put the blade down what is wrong?

Sounds like the pulley that spins the blade is stuck. When the blade is lowered, the belt tightens on the pulley and spins it. If the pulley is stuck, it will not spin and the belt will "squeal" as it tries to spin it. The extra load that is added to the engine when the belt is trying to spin the stuck pulley is a bigger load than the engine can handle, so the engine stalls (stops). Check the blade pulley - or it is possible there may be some debris under the deck that is preventing the blades from turning.

When the bail for the the blade clutch is pulled back, against the force of the return spring, the blade is engaged with the engine crankshaft allowing it to spin. When the bail is released, the spring snaps back and the clutch disengages the blade from the crankshaft and stops the blade.

What is deck cleanout on a lawn mower?
The deck on a lawn mower is the shaped metal shroud that keeps the spinning blade(s) from being exposed to the user during operation. Many manufactures use the shape of the deck to create a mild vacuum that draws the blades of grass up toward the mower blade(s). After mowing the lawn, some grass will be stuck on the underside of the deck. If the lawn is somewhat long and wet, the grass will build up on the inner surface of the deck to a point where only the blade(s) have clearance. This stops the deck shape from performing its designed function. Deck cleanout is performed while the mower is NOT running. Turn the mower on its side and scrape the excess grass from out of the underside of the deck.

How do you bypass the seat switch on a Murray riding mower model 3090078xb?
The seat safety switch is there for a very good reason, like say if you fall off the mower it stops and doesn't continue driving to run you over, or simply starting it standing beside it with your foot under the deck. If the switch is broken and you can't get the mower started though just use a jumper-wire between the contacts so the electrical current is complete, simple really.
