Hi guys and girls

I have a problem with my xterra.. i haved been in soo many mecanics
trying to figure out the problem...

soo this are the details

When running is fine but when i stop at a traffic ligth when i hit the brakes the engines starts i mean the rpms start to go up and down engine is failing
and shuts down .... it happens only when i hit the brakes or i stop accelerating

in the computer doesnt show any error codes... plus is not he fuel pump, the spark are new. i have tryied everything

TPS but that usually throws a code. Try some seafoam in the intake.

it doesnt show a code
thats the weird part

Will the X fire right back up after it dies or does the engine have to completely cool off before it will?

I'd check for vacuum leaks to the brake booster and on and around the intake manifold.
