I have a 1996 Mercury Villager and battled this problem for years. My van would stall on hot days, at high altitudes and sometimes just randomly (even on the freeway which posed considerable dangerous situation). Several dealers and mechanics could not diagnose the problem. I finally had the fuel pump replaced and the problem has not reoccurred. However, I agreed to use an after-market fuel pump and it does not give accurate fuel gage readings. You might want to consider using the dealer brand (which was considerably more expensive).
