Tire/Tube Issue
I'm having a problem since I started using new tires.
Am riding a hybrid and since I only ride asphalt, I changed out the tires from 700x38 knobbys to 700x32 Panaracer Tserve Pt. Had them put on with new Bontrager tubes by a local well known bike shop in Austin. (They recommended these tires for my wheels which are 622 x 18)
Here's the problem: At 8.5 miles the front developed a hole in the tube which was replaced by the bike shop the same day. Another 4 miles later the rear developed a hole in the tube which I replaced. Another 6 miles later the rear again has developed a hole in the tube. Three tubes in under 20 miles, while before I switched out the tires I had ridden almost 1000 miles without a flat. All tubes (with these new tires) are Bontrager 700 x 28 to 32.
Question: Has anyone had problems with either Panaracer Tserve tires or Bontrager tubes? I'd rather be riding than being sidelined with flats.

Can't speak to thes particular brands but where are the punctures happening and what do they look like? Often, multiple flatting in a short amount of time can point toward problems with the rim, rim strip, installation methods, running under inflated or something being stick in the tire.

The first hole was along the rim and inspection showed no probs. 2nd & 3rd hole on sidewall - no foreign material present. These are not slow leaks, tire goes flat very fast. Tires are supposed to be flat resistant.

It would help us a lot here if you could tell us where the holes occurred on the tubes.
If the holes are occurring on the back side of the tube then you got an issue with your rim strip. That's a cheap and easy DIY repair.
If the holes are occurring randomly, in no particular area, the LBS may have sold you bad tubes.
If the holes are occurring in the same area on the top of the tube then you have something stuck in the tire that's poking it. Find the object and remove it.
If you have the holes occurring on the side of the tube in the same area, it could be from something stuck in the sidewall of the tire poking your tube, maybe a piece of the beading is intruding inward poking the tube, or maybe you have a damaged rim with a slight nick of metal poking at the tube. A nick rim is easy to fix just run a fine file over it to take the sharp edge off. If the bead has a problem you might be able to cut the offending obtrusion off the bead. If something is stuck in the sidewall then just pull it out.
If something is stuck in the tire it's not all that difficult to find it, either look real closely at the outside and the inside of the tire in the area where the hole occurs on the tube, then see if you can feel anything, if those methods fail take a cloth rag and run it on the inside of the tire of that area and see if the rag catches, or drags on something.
