Cam retarded off? Do you have any codes like p1345?

Sounds like its sucking air somewhere my old truck did the same thing but it was carburetor

Sounds like you have a bad coolant temp sensor (computer one not the gauge one) thats how my old jimmy ran probably flooding it out. Cheap part, $13? Should go up by the thermostat housing
