Craftsman LT1000 ridign mower engine dies after 15 min-deadman on

My riding lawnmower engine dies after 15-20 minutes. The deadman switch under the seat is connected as good as it can be. It seems like something is getting too hot and it kills the engine. Could it be the wiring of the deadman switch needs replacing??
I have changed: fuel filter, partial fuel hose, oil & oil filter, air filter, belts, throttle lever (maybe not set back correctly?) and put water remover in the gas.. What now??

There are several things that could be going on, but what you said in your description about the dead man switch in the seat may need your attention first. The switch it self could also be bad. After you rule this out the next thing I would check is the fuel shut off solenoid located on the carb when you turn the key on to run you should hear a click and feel it in the solenoid. After this you may have a fuel pump issue or a coil issue. but from what you I have described I believethe first 2 itmes I mentioned should fix your problem

Your problem is very simple....loosen your gas cap and let some air in the tank then tighten back up and it will run like a charm....about every 30 min. of use just loosen cap a little and repeat....sounds crazy but an old timer mechanic told me about this and it worked...no more problems.....good luck

There are other safety switches as well. The electrical diagram shows (2) of the interlock switches (part no. 16 in diagram) in the electrical system. The location of the 2nd one could be on the transmission or the clutch/brake pedal. It could also be on the PTO system (blade actuator if you will). See if you can find the other switch on your unit. I have an LT1000 and have NOT looked for them. Here is an electrical diagram on your unit.

Craftsman riding lawn mower 42 will not stay on after taking foot of brake pedal


the "safety deadman switch" is the problem, however, we call it simply "the seat switch" - flip the seat forward and you will see wires going to the middle of the seat, the connector is probably slightly unplugged - wiggle it back on to make a good connection - this is a verry common problem [the unplugged switch is telling the tractor that there is nobody on the seat and it kills the engine]
