Blazer bogs out runs fine for awhile and bogs out again
Check engine light on ?
Have you checked fuel pressure with a gauge ?
Po138 replaced pump on 4/7/16 still doing it

So again, have you checked fuel pressure with a gauge ? And did you change the filter when you changed the pump ? Vortec engines require at least 65-70psi to start and run. Some aftermarket pumps are not up to the task.
And just for the record, code 138 is not really connected to the fuel pump.
