My van stops running when it is hot outside and it seems like it is vapor-locked. After the sun goes down it runs again. It seems like the fuel just shuts off and it is stranding me after I have driven for only a very short time in the afternoon. In the mornings it seems fine but by 11 am it will shut off and not start for hours. I have replaced the fuel pump, the plugs, the gas cap, added cleaners, had various certified mechanics "fix" it only to spend hundreds of dollars and be stranded again.

Now I started it up and it ran for about a quarter mile before it stalled and would not start again. I heard from one mechanic it could be something to do with the distributor cap, another one told me it could be something with the started and then the suggestion that there is a nylon sock filter inside my fuel pump that is closing around the line and causing the failure. I had the oxygen/fuel sensor replaced and it did not help. Could it be my fuel injectors? How will I know? I have been ripped off for a total of $820.00 and still no fix.
