I tied the vacuum line directly to the intake manfold. I think the issue is related to the pot. When the pot is set at below.3/.25v, as read at the ECU wire, then the problem occurs most of the time. The pot will not give a full sweep of.25 - 4.7v.
If the pot is set at.5 -.7v idle, the problem is less frequent.
Thank you for input Jplayer
