question: DT 200 EFI motor runs good. then when slowing down kicks on and off and motor stops.when I wait a little while the motor starts back up and runs great with no problems. what could it be?

dt200 EFI, decelerating problems

You don't mention year model?
Does your monitor gauge flash any codes?
When slowing down, motor turns on, and off, then stops? anyone worked on controls, wires, replaced any parts of control recently? Kill switch loose, or damaged/ replaced?
Does this happen only if slowing down quickly, or just slowly?
You mention waiting to restart, reason for waiting?
is this problem new, or did something change that may have initiated this? Different fuel, new battery, new fuel lines...etc. Do you have to pump fuel bulb to restart?

I know, lots of questions, but we are listening.
Just trying to feel out your problem here.
Many that post problems, do not realize they have to be our eyes, ears, hands, etc.. But, without their/ your help it is difficult to identify your particular problem.
Let us know, good luck.

no just motor cuts out but it will crank wont start unless I wait 20 min every thing else works

The time you are waiting, 20 mins, is suggesting its heat related, check for possible vapor lock in a fuel line next to the engine first, then start looking at ignition components that maybe heating up also check your charging rate to see if its over charging slightly.

Think I would check neutral switch, to rule it out, may be shorting out, or one of the wires shorting.
The 20 mins wait time makes me think heat related, or pressure related also.
Can you tell if high pressure fuel pump is running after it shuts down, during that 20 mins?
