Over the past month, the Spider has developed a rather annoying problem. On a hot day (let's say mid 80s or higher) after driving awhile, it will all of a sudden "cut out" or "miss." This only happens after driving for about 10-15 minutes, and the actual occurrence only happens for a second or two (car never stalls out). After an occurrence, the car will run fine for another 5-10 minutes and then it happens again. I've intitally pegged it as an ignition problem, since if you press on the gas itthe car goes, unlike a fuel problem. I know it's not a small vapor lock, as the fuel lines are pressurized (fuel injected). It usually happens if you've been cruising at a nice intermediate speed (45-60mph) for a few minutes and then LIGHTLY touch the gas.
I thought it was probably similar to the one I had when I first got the car where the coil was shorting out internally when it got hot. However, after swapping the coil and module (Delco ignition), the problem is still there. Next was check the distributor cap and plug wires. Cap had "score marks" on a couple of the contacts, so replaced that. Rotor looked ok...cleaned it off and put it back in. Put on the spare set of plug wires I had. Spark plugs (Bosch Platinums) are new last year and have less than 2000 miles on them. Still happens.
What else can I look at. Other than this, the car runs fine.
