Well the verdict is in.... and almost by accident. I've been driving the GMC daily to work, which is only a short distance, to see if this "pause that makes your heart skip" continues. Tonight I found the problem and luckly kept from crashing for lack of brake boost.

As Paul Harvey use to say, "now the rest of the story, stand by for news".
Leaving work tonight I decided to go the long way home to see if I could get a hiccup. Actually I drove a couple extra miles instead of the few blocks from work to home. I was going to wait 'till the weekend to dig into the problem but wanted to see if warmed up on the longer drive made a difference. Well I was going about 55 on the old business 99 hiway and was approaching the turn toward home and lost all power, but unlike the bird strike NY flight that landed in the Hudson, I had no one to call in my Mayday. Full flaps, I hit the brakes and not much there, no vac, immediately to second and made it around the turn rather easily, but the thing coasted forever it seemed like. It was a good thing that nobody was in front of me going slow or they would of had a rather noticable push!

Now at the side of the road I hit the starter and nothing, well to0 far to walk so I decided to pop the cover and have a quick look before calling for help and a pull home. First I checked to see if I was getting fuel, top of air cleaner off, pushed throttle saw fuel so must me electrical. Started at step one, battery to distributor/tach connection........ can you believe it the clip was partially unplugged (loose)! Now I know I plugged it in from before but didn't check to see if would pull out easily, but I do remember I was hard to get out when I worked on the distributor last weekend. The metal clips inside must have bent and lost tension to hold it in. Let this be a lesson check connections for tightness. I then drove for at least 10 miles stop and go and freeway to see if I had fixed the previous problem of the intermittent pause, no problems, I think that the loose distributor power wire was the problem.

Now I am going to attend to the no brakes with a dead engine problem I experienced tonight. I have a auxiliary vac storage tank system that I got from Jim B awhile back. I never got around to hooking it up, but after going around the turn tonight on three wheels, it's on the top of my list. It's a 4"x36" pvc tube plumbed into the booster to provide for a few extra pumps of the brakes. Maybe Jim if you are reading can tell the others if you are still using and selling the kits, it seems a lot easier and reliable that a booster pump that may or may not be working. If not Jim maybe someone else want to pick up the subject and start a new post to discuss the topic! I sure like stirring the pot but I'm off to say my prayers. Good Night!

Like usual, one problem solved, another new one.

Thanks to all for your thoughts
