Loren,
     Spot on Loren that was the problem.   Thanks for the tip.  Problem started after I took it to be smogged.   Guess they bumped the knob climbing in and out of the van.   Failed me on the gas cap and charged be 45$ for the fix.   Good reason to carry an extra gas cap in California when you do the smog.   Thanks again, Gary
