1996 Caravan stalling problem

I have a 96 Caravan that recently started stalling. Codes 12 21
55.....oxygen sensor has since been replaced and codes cleared. However,
the van is still stalling, and no codes are showing up. It stalls while
driving, the van just dies out and takes 1 to 3 min to restart. I can
drive it for hours and no stalling and then all of a sudden it will stall.
I have brought it to 4 mechanics and none of them can figure out the
problem. Please help! Any suggestion will be appreciated.

 

If you have the 3.3 or 3.8, I would suggest checking the camshaft and
crankshaft sensors. Also, has the fuel pump and fuel filter been
checked?

Assuming that everything else is in proper running order (i.e. no fuel or
ignition faults) it has been my experience that stalling is most likely
caused by a sporadically malfunctioning computer control module. Contrary to
what the manufacturers claim, these devices are finicky and prone to
misbehave because they are expected to perform flawlessly in every kind of
weather conditions. The computers are manufactured with cheap materials and
can be expected to fail sometime during the life of the engine.
Unfortunately, these are also very expensive replacements.
