S-10 Blazer start problems

i have a 91 s-10 blazer 4.3l anyways... it is having a weird starting problem.. like if it is cold it will almost always start fine.. but after u drive around for a bit then let it sit for like 10 mins it takes a while for it to start... it will just keep on turning without anything happening then after like 30 secs it will start but start really rough then after another second be fine... any ideas?? i was thinking the fuel pump was bad but i dont want to have to take the tank out and replace unless i have to.

Also i replaced fuel filter...

Yip, check your fuel pressure and check your battery voltage both when running and when the engine is off.

Test the voltage with a voltmeter, NOT the dash gauge.

Also check and make sure the injectors are not leaking after the engine is shut off.
