My issue....awhile back, 6 weeks or so, I fueled up forgot to put gas cap back on and noticed it when I heard it rolling on the road. Went around the block, parked let the car run grabbed the gas cap off the road and put it back on. When pulling away from parking spot car ran like total crap. Stumbling all over itself to the point it would die. Was able to get it going after awhile and drove the 10 miles home with no issues. Fast forward to a month ago. Again, stopped for fuel and took off. Car was running fine until 15 miles later. Car again died and started stumbling all over itself. This time was not able to get it going so I had to get a tow. Couple days later when I was able to look at it, hit the key and started right up. Last week Sunday, fueled up again, left gas station made it about 1/2 mile and it died. Once again stumbling all over itself. Pulled air cleaner hit the throttle and gas was shooting in carb no problem. Was able to get it going and drove the 25 miles home. Car ran great!!! Seems to me I'm having a vacuum/vapor lock of some sort after getting gas. Car has new tank, fuel lines, fuel pump and the fuel filter is nice and clean. My fuel line is routed well away from heat sources. Like I said, in between these issues the car is running great. Let me know what you all think I should be looking for. Thanks
