1981 EZGO Gas 2 Stroke starting issues after a hard run

[yler4cy]

I have a 1981 EZGO Gas 2 stroke and for some reason if I run it hard for awhile the next day when I try to drive it it seems to "turn over", sorry I don't know the correct verbiage, but it won't take off. The last time this happened I noticed that there was no fuel going to the motor, because it has a plastic fuel filter on it. When I pulled the hose off the fuel filter and pushed down the gas it started to take off. I connected the hose back to the fuel filter and it ran fine. I took it to a local shop and he said that there was a small pin hole in the gas line. He replaced it and it ran fine. Well I ran it hard once again yesterday and last night and now it is doing the same thing tonight. I didn't try to pull the fuel line this time as it was getting too late to work on.

Any help would be greatly appreciated.
