Which sensor this time???

[craigrpowers]

Hi all,

Let's play a little game called which sensor is it?

1994 k1500 5.0 on which almost everything has been replaced. Been running great, then today stepped on the gas and lost power momentarily. Let off and idles perfectly. This continued until I restarted it and was fine for an hour or so, then again with the loss of power. Did a rolling restart and back to fine for awhile... what'cha all think? TIA

im thinking bad fuel pump , have you checked fuel pressure

I had that thought and I know it's a fairly common issue. The restart straightens it out for a time which makes me think sensor. Sort of leaning trans speed sensor as all at the throttle body were replaced a month or so ago when rebuilding the tbi. If I can get it to fail in the driveway, pressure test on the list. Thanks.
