need some help

Just got my motor back in from putting new bearings in the bottom end after an oil cooler failure... started it up, had oil pressure, ran mint. All of a sudden it died and now cranks over real slow. Yes, I put the right size bearings in and used a good assembly lube as well as torqued everything properly. It was running extremely good actually, just randomly died and now cranks over very slow. No unusual noises came from it at all when running. Ideas? Ran for about 2 minutes

Fuel and oil pressure?

 

[swamp_ratt]

Yup

Would batteries cause them to just randomly die like that?

 

[Magnum PD]

No voltage, yeah

I kinda have a feeling it's a combination of batteries/starter and still air in the fuel system (both oil and fuel sides) my gut is telling me not motor itself

If it spins and not locked up, should be ok.

Yah, I was able to turn it over by hand ok, tried it again just cuz I was pissed and didn't care, got it started and it huffed a ton of smoke out the oil cap and pcv system (air filter assembly is not on at the moment) for about a minute. Heavy at first and slowly faded, then it went to normal and is running fine... I don't get it...
