Chrysler Repair: stalling when engine is hot, senser, gas filter

Question
I have a 1995 Plymouth Voyageur with 150,000 miles on it.  Don't drive it much (a third car).  Used to drive kids stuff back & forth to college.  When on last long trip, engine cut out (no power to steering, brakes etc) during extended highway driving.  Happened twice. Restarted after we pulled off highway and waited a few minutes.  Otherwise drives fine.  Has passed safety etc.  

Answer
hello maret
this should have a diagnostic test to see if i am wright it could be a bad gas filter or a bad 02 senser or a bad cam senser so it could be one of the 3 things what i have told you . so i would bring it to a good shop to see what of the 3 it is pete
