My 1990 GTR was fine a few weeks ago, only work that was done was that we removed the airbox and both AFMs and tightened down a loose bolt on the charge pipe to fix a leak.  Put everything back together, warmed it up for about 20 minutes (cold here now), then took it out.  When coming up to a stop sign, rather briskly, the 4wd and Anitlock dash lights came on followed by a complete loss of power.  Car started right back up just fine and does not lose power when its moving forward, only when stopping, and its random.  More frequently than not though.  Any thoughts on what the issue could be? Car is all stock.

Thanks for the tip, opened opened the first one and looks ok, but put some new fresh solder on the connectors since I was in there.  Gonna open up the second on and take a look tomorrow.  Hoping that fixes the problem.  I'll post an update soon.

Problem has been resolved.  Stepped back and thought about this issue logicially...the problem that was seen was symptomatic to running out of gas.  The car has a full tank so thinking the problem was due to fuel delivery.  Checked all injectors and all were good, and then changed the fuel filter out.  After draining the fuel filter into an empty water bottle, it was completely black with chunks of gunk coming out of it!  I'm thinking that the fuel feed was being restricted due to the old fuel filter, causing the car to stall out.  Just my .02 cents but at least its working now without the constant engine shutdown.  Also cleaned out the IAC valve and replaced the non-existent gasket.  This may or may not have helped, but couldn't have hurt since it was covered in carbon.  Hope my situation can help someone out!  Pictures of what came out of the fuel filter attached.  Thanks!

      RB25DE NEO with Haltech ECU

      If you take the top half of the intake off you can unbolt the flap off the shaft and leave the shaft in there blocking the hole. Then you can remove the little vacuum canister off from under the manifold and get a spare vacuum line to run to the ECU. I can take some photos of it later. Probably best to get the vacuum source to the ECU sorted first though. Mine all worked mint with the base map from the GTT an I've pretty much let the closed loop sort the fueling and took 1 degree out of the whole timing map.

      This IS something you also have to configure in Haltech (or at least I did in the past when going from onboard-to-ECU map sensor and an external MAP sensor in haltech land).

      I'm hoping it's something as simple as the ECU is looking for an external MAP sensor, but he is trying to use the onboard MAP sensor.

      You won't need to do that if your happy to learn to tune it yourself. You 100% do not need to do that. It is not part of the learning process. It's not like driving on track and 'finding the limit by stepping over the limit'. You should not ever accidently blow up an engine and you should have setup the ECU's engine protection to save you from yourself while you are learning anyway. Plenty of us have tuned their own cars, myself included. We still come here for advice/guidance/new ideas etc.  What have you been doing so far to learn how to tune?

      Put the ECU's MAP line in your mouth. Blow as hard as you can. You should be able to see about 10 kPa, maybe 15 kPa positive pressure. Suck on it. You should be able to generate a decent vacuum to about the same level also. Note that this is only ~2 psi either way. If the MAP is reading -5 psi all the time, ignition on, engine running or not, driving around or not, then it is severely f**ked. Also, you SHOULD NOT BE DRIVING IT WITHOUT A LOAD REFERENCE. You will break the engine. Badly.
