Unknown Engine Problem - HELP!!!

[mrtew]

My VX does this every few months. If I drive to several places and it sits in the sun on a really hot day for about 5 minutes while I run in to some store when I come back it starts fine but then stalls several times in a row. Finally the revs will stay up and it gets back to normal and I don't see it again for a long time and forget all about it. It's good to knowI'm not the only one and it would be even better to find out the cause and cure!

replacing my fuel pressure regulator and fuel filter got rid of the problem for me.. exactly how you described it but for me it was a weekly problem. the odd thing though is that mine seemed worse in the winter time

I doubt heat is the issue. I live in BHC which is in the middle of the Mohave Desert (for those who may not have heard of it) are summers are always in the 110 degrees plus. Last summer we had a dozen days in a row where the temp was in the 120 degree plus area and over 100 at night. Never had this issue. That being said whatever the issue is may of course be complicated by heat.
