advice on truck dying while driving

[basspap]

hello just got a 86 c10 and put new fuel pump and a rebuilt quad 4 barrel carb, starts up good, idle sounds good, start driving around after 15min starts to bog down when push on gas if let up it stays on .if dies, u have to wait for a few minutes to be able to start again. don't know if it just needs to be adjusted correctly or should i start looking for other issue, i haven't change spark plugs or cap yet, was leaning to fuel issue first. any help would be appreciated

does it bog when you start to drive it and idling is always ok? When does the bog occur?  Are you talking about tip in (opening of the throttle) and it almost dies?
Could be a bad accelerator pump... Need more specific information..

the whole 15 minute cool down deal seams like its electrical to me. but when it does this are you able to come to a stop and the engine still be at idle?

     Have you checked the fuel filter ?  Paper filter before they become completely clogged will build up and then clog, then as you let them sit the contaminates settle allowing some of the filter to free up again.  Once this happens you can run it for a certain time and then it plugs up all over.
     Try changing fuel filter if you have not done it yet.

Hey sorry for  getting back here late, thanks for comments, it was the evap was bad putting charcoal into my fuel pump, getting no gas into carb, runs great, but new problem after driving for 15-20 mins truck doesn't want to start, not even turning over sounds like lack of power idk

Sounds like the starter is going bad.  Once everything cools down, does it start normally?

Man that drove me insane when my starter wouldn't work when it got hot, wrapped it with the DEI heat wrap which fixed it until it hit 100* outside and sure enough if I drove for more than 20 minutes it wouldn't start for another 15 minutes. Replaced starter with a big block starter (has metal solenoid instead of plastic) and wrapped it again and no more problem. My dad refers to this as "heat soak", when the motor and exhaust is hot and you shut the engine off coolant no longer circulates and the fan is no longer on leading to a spike in the temperature which then soaks into the starter solenoid overheating it and rendering it useless until it cools off, which is why the starter always tested good.

I've seen some
With a fan and ductwork added to cure this

The fan was pulled from a f-150 with the 300 six
Converting it to a ford type relay on the fender helps too

Yes once it cools down it will start right up, starters $30 so I will swap that out and see what happens, thanks

You might want to go for the later high-torque starter.  I don't know the number off-hand, I haven't had to do that research myself yet, but I think beginning in 1996 or so there was a smaller high-torque GM starter that resolved a lot of problems in the earlier units.

Somebody else who knows chime in please, so he can get the good one.
