probably vapor lock, the fuel lines are running to close to the exhaust manifold or the heads..next time it happens pour some cold water over the fuel pump if the problem goes away then for sure it is vapor lock.

Definately make sure the fuel line is not routed near heat sources including and especially the radiator hose/thermostat neck on the intake. I would also check to make sure your choke is adjusted properly and coming off when it should.

I have the same problem with my 66 (289 2bbl). If I park it for 5 minutes on a hot day it just cranks over. I don't think my problem is vapor lock though. Instead the gas in the carburator bowl starts to boil causing the carburator to flood. I was thinking the engine might be running too hot because I could hear the coolant bubble a bit. Fortunately it does start right up when I hold the throttle open and clear the gas out. Oddly enough it never acts up when the wife drives it. Must be a girls car.

I had the same problem in my 66 289. What I did; I put a 1" phenolic spacer under the carb. I bought a 800 C.A. battery from Walmart. I bought a NEW stock starter from USA Industries that turns the engine over 3-4 times faster than any other stock starter. The starter was about the same price as you'd pay at Advance about $39.00. The battery was $72.00 and the spacer was about $30-$40. Now when I would normally have a hard start problem, the starter turns the engine over so fast it starts up in 2-3 seconds!
No I didn't. I bought it from a local Mustang supplier. It looks like you can buy it direct from them though according to their web-site. Or if you want the Mustang guy's # I can get that for you. I can say this much about the starter. I have never had a starter that would turn the engine over like this one. When the engine is cold, you just touch the key and it's started, there's no cranking at all!
DB Electrical has mini starters for about $60. Cranks my 347 (16 degrees initial timing) over just fine even when hot. The stock starter could not do that.
If you have hood clearance problems there is a 3/8" insulating spacer made by Edelbrock. Part #9266 from Summit, $20.
