SOURCE: Engine management fault
this is going to sound nuts but its true.if your brakelight switch is defective that light will flash.
see if you brake lights are working.if it is automatic trans you will notice the shifter will not always release when you depress brake pedal.
if its not brakelight switch get it autoscaned with a VAG.com

Take a good close look at the rubber strip between the windshield and the plastic shroud the wipers are mounted in. If it is not a tight seal on the passinger side water can run down and get the Pcm wet. When the Pcm gets just a little water on the connector it can cause the problems you describe. If it gets alot of water on it it can and fills the Pcm up, then you will have major problems. It will set error codes for everything and anything.
This is a defect in the design of the vans and the only way to fix it is to make sure that this rubber seal is tight against the glass (especially on the passinger side).
I had to have my Pcm replaced because of water (not a cheap fix) and the dealer did what Ford recommends. It filled with water again. After the third try I gave the dealer a piece of an inner tube from a wheel barrow tire and had them place it over the connector and seal it against the fire wall. Then I used aquarium sealant and glued the little rubber strip to the windshield.
I haven't had any more problems since.
The Pcm connector is probable the most critical part of the electrical system and they placed it in the worst possible place.
Ford knows of the problem but will do nothing to fix it.
Mine cost over $800 to fix, but believe it or not my insurance paid for part of it because it was water damage.

check to see if your brake lights are working.usually the stop light switch fails and is the cause.but before buying a new one check the stop light fuse.its a common problem with a simple fix.hope this helps.

the car is going into limp mode due to an engine management fault. have to check what the fault is with a code reader. if the milage is high 100,000+ could be a turbo fault (overboosting), as this will put the car into limp mode.
