A little help? Stall issue, 914 1.7L 1971 Options

Good afternoon Guys,

I had my car put away in the winter. Took it out about 1 day in March ago on a 40 degree day and it started just great. Drove about 10 miles and shut it off. The next day it didn't start . I screwed around with it to no avail.
Saturday a Volkswagen guy came to the house and we changed all the plug wires, new plugs (gapped) cleaned the distributor, set the timing, pulled all the injectors and cleaned them and replaced the injector hoses. Started it up and although it "hunted" at idle once I drove around it was running fine. After about 10 miles I lost power, it was like there was no throttle. I waited 20 minutes and it started and ran about a mile and would lose power again. It did this about 5 times and then it ran good again.
I was thinking it sounds like "vapor lock", but it was only about 70 degrees here in Milwaukee I didn't think the vapor lock would happen multiple times.
I toped the tank off with new Premium fuel.
I checked my compression and #1 plug was 90 #2 90 #3 80 and #4 was 70 but those readings were before we got the engine started so I would expect them to be low.
Any ideas?
As always, thanks for your help.

Thanks guys, the Volks guy said I should pour a shot of Sea Foam in the spark plug hole and let it sit for (2) days then change the oil. I looked at it last night and found the oil level in the air cleaner was almost nil. I added oil and drove it for 30 minutes at road speed and about 15 minutes on the highway. It ran pretty well. Had no problem hitting 80mph. What do you guys think about Sea Foam? I've read some that say it is not only not good but actually bad for an engine. It seems it is a solvent and if I change the oil after a two day soak it could clean and help with the compression. The car has been idle.
Your thoughts.

cheers!
