Question:
The problem does not happen every time I drive the van, never know when it will act up. If I let it sit for awhile, it starts up again.
This has happened at the service center but they are still unable to find anything with diagnostics.

Sounds like the "techs" aren't trying very hard, or else they're clueless. An intermittent problem like yours is admittedly much harder than usual to solve, but still needs to be approached in a logical step by step manner. If all they're doing is looking for codes, then I sure hope you didn't give them any money. If you see anyone at that place with a MODIS or Vantage Pro, go and talk to them right away. Just using the Tech II isn't gonna get it done. Use the low amp probe on the fuel pump relay, that's AMP not volts, display that trace (channel 1) with the fuel pressure (channel 2) and go for a test drive. Look for jagged commutator spikes consistent with pressure fluctuations. This will give you an idea of pump condition, and on the off chance the failure occurs on the test drive, the evidence will be right in front of you. Also, note that the check engine light (MIL) doesn't come on. Use channel 3 with the KV probe and graph the coil output. It could take some time, but waiting for the computer to figure it out instead of using any intelligence or training is just a crime. I never understand how these clowns call themselves "technicians" yet consistently fail to check the basics. Oh, and the quick and dirty way to monitor fuel press is just hook it to the rail, run the hose out of the hood, and zip tie the gauge to the wiper. Not pretty, but will show if you do have a major fuel issue. As for the ignition, use a see-thru tester that lights up. Can get them for 5 bucks, stick 2 of them on adjacent cylinders, then if the engine quits, have someone crank it while you look for the lights. Easy. Lemme know what happens. And as far as "jeep"'s answer, yes that could be a possibility with your vehicle, or a ground strap, or maybe not. If your engine quits with or without a drop in fuel presure, it will at least give you a place to start.Volkswagen golf gl mk3 1995 automatic What is the recommended power steering fluid?
