vacuum lock issue?

[supraluver4life]

so about two weeks ago my car has been acting up (what a supra lol). Im really confused about the issue. So i go to start it up in the morning and it starts up fine i drive into town (which takes about 30 min) with no issues. Then i go to start the car up after letting it sit for 10 minutes and it just turns over and nothing!!! but then if i leave it to cool down for say like an hour it turns over and starts right up. Funny thing is, i think it got worse yesterday. I drove into town, stopped at autozone, and then went to turn my car on and it didnt work. Same issue so i left it for an hour tried again... nothing! so four hours went by and i finally said screw it ill come back and get it tomorrow, so we were rolling my car back around to the employee parking lot and i just randomly tried to roll start it, even though i knew if the starter doesnt start it roll starting it wont do shit. Then bam it roll started and ran fine. So i drove it home and parked it for a while. So theres my problem, some people have said that it sounds like a vacuum lock issue. Anyone with any ideas on how to fix this please chime in... because for now its just another supra sitting in someones yard
