My van keeps cutting off and i dont know what to do

throttle position sen. or egr valve, get autozone to scan computer to see

The warning lights on the dash will come on when the engine dies.
If it dies and starts up like you turned the key it could be a relay or other electrical problem. May be tough to find if you can't test components while it is not starting.
I assume the check engine light is not on when the engine is running.

Replace the netral safety switch

take it in and have the fault codes read
when engine lights start flashing that is the time that you look immediately to have the codes read

i need to know wich engine you have. if it is an 1,6 or 1,8 litre zetek or 16 v check the sensor at the gearbox

it could be faulty fuel pump or coil pack transistor.

try fuel filter first.

dont not cut any wire find a alarm technician and ask them disable for you unit is link to vEhicle ECM DONT CUT AND FOR THE SAKE OF CUTTING MAKE SURE THIS DONT BY SOMEONE WITH KNOWLEDGE

sounds like transmission
