Thx to all you guys who responded to = my problem of the intermittent sputtering problem of taking off from a = standing start.  The problem did not occur all the time and did not = occur every day.  It seemed more likely to occur on hot = days.
My solution:  add fuel cleaner = to tank of gas; and replace the fuel filter.  Today I tested the van in hot = weather (95 degrees) under stress with lots of stop and go driving as well as = freeway driving.  IT'S RUNNING GREAT-today!!  I'll see how it does = over the next few days.
 
Thanks to the nine of you who = responded to my plea for help.
