When my 1999 chevy venture gets warmed up it shuts down when I come to stops. I can start it right back up and continue on my way. Why is it shutting down?

Might have clogged catalytic converter.

According to the auto parts listing, I am showing one converter. The discount price is around $200 plus labor.
I would get a second opinion.

The module may have failed.
The module reads the chip in the key thru the sensor in the lock cylinder.

take your starter out take to local part store they will check for free

it sounds like the fuel pump or fuel filter

Your right to think about gas but the fuel pumps fail all kinds of crazy ways. The easy way to cheack to see if its the pump is to listen to the tank ( with your ear right against it ) and turn the key on to here the pump come on. If you don't hear anything and the hearing it'self is OK then with someone trying to start the car bang on the tank to shake it and see if the pump will come back on (sometimes they quit altogether and this won't work) The vehical may start right up. If it does the pump is still bad even thogh its running and may not restart as early as the next ry or even quit while running as it already did to you. Rember evven though the gauge says theres gas there may not be be as someone could have stole it and the gauge got bent during the theif. Do'nt look in with a lit match just cause you saw it on TV. Shake the car with a funnell in the fuel cap and listen for gas slushing around. Nothing or slight your out. Listen for the pump this way as it'll really hum in the funnell even full of gas

need to change your wiper motor.

sounds like timing cover or water pump

You will need to replace the wiper transmission.This is a common problem.

check to see if all doors are shut tight,the same thing was happening to me,and it was the very back door that was the problem
