Default Help! Loss of Power/Won't restart

So there I was...off to get some exhaust work done this morning and it died on me.

Background: It's been running sluggish and at times is hard to start. This morning it took a couple minutes of stumbling to get it going. When it did get going, it felt like it was at half power. Then it just cuts off completely. I coast into a parking spot and have to park like a dick (two spaces).

Another symptom is that it takes a good second or two to shut off after I switch the ignition off.

It's a 2.8 TGV with about 2k miles on it.

Tow truck is on the way. Unfortunately we just sold our house and are waiting to move into our new one so no access to garage or tools

...thoughts? IP?

First thing that comes to mind........ Check the connection of the wire at the fuel stop solenoid on the IP or perhaps the solinoid itself may be your issue.

Engine doesn't catch or doesn't turn over?

Follow the systems path for the things needed to make the engine work and one or more are the culprit:
Ignition - failing ignition switch
Injection - fuel flow issues, vacuum leaks, dirty/wet fuel, timing, tank breather
Electrical - power to solenoid, solenoid operational, factory alarm system
Air - clogged intake, oil leak past cyclonic breather, oil past turbo bearings
Compression - head, engine, etc...

@ only 2k would start @ filter flow or air leak on suction side issue. They dont run well on compressed air.

Ok, well...didn't turn out so well and had it towed to Olivers Automotive, a local RV mechanic.

I did get it to restart and then once it shifted into 3rd, it bogged down and shut off again and wouldn't start. This was at a busy intersection. Police showed up and I eventually got it to start again by cracking an injector. Prior to that I cracked the bleeder screw on top of the filter housing and turned it over a few times...fuel came out.

I recently started driving this and noticed that when it did run, I could barely get up to 65 and maybe 50 up a slight highway incline. The 2.8 should have more balls than that. Granted I have an ZF auto, but I also have a 1:22 TC.

Stumped...I hope Olivers can find the culprit. Maybe like Uncle Douglas said..an air leak suction side.

I did the click test at the fuel stop solenoid and it clicked as it should. Again, I was limited to tools but

Turns over fine...won't catch. When it eventually does, it stumbles to life but it takes a long time.

Air filter was good, was getting fuel at good enough pressure at the injector to spray the inside of the raised hood.

A friends truck started having similar issues. It was a poor sealing fuel filter. Use a paper towel corner on the filter lip and see if it becomes wet. If so it’s a cheap fix.

Man I hope it?s something small like that. It?s a kick in the pants to finally get it on the road only to hold up traffic and get gawked by Jeeps lol

Sounds like fuel issues - lift pump failure is possible, or if no obvious fuel leaks, the vacuum side of the line is probably picking up air,. Alternately the timing has moved and the fuel is not being delivered when needed.

Agree-fuel starvation comes to mind.
