My 1992 Acclaim seems to be cured. It was stalling 20 minutes after going on the road, with perfect regularity. This started right after getting a new fuel pump.
Then on a very hot day, it wouldn't start at all, but it started with ether. So I had it towed, but after the tow it started by itself, and ran ever since. The mechanic drove it for a few days with a fuel pressure guage taped to the windshield and said it remained normal.
Maybe there was a blockage that got cleared when they put the guage on. Who knows?
