I may have figured it out. Getting new fuel pump relay after jumping it and getting it running.

1998 S70 running great until I used compressed air to blow out air filter box.
I replaced mass-air flow-sensor (MAF)with "unbrand" and ran about two weeks then failed. Got a Bosch and ran about two months then failed. Got used MAF from junk yard, ran a couple of minutes.
Got new Bosh and wont even ...
