xj6 III losing power suddenly
So I Experienced this 2 times today during my commute.
Commute is 50 miles each direction.
The first time it happened it was just for 1 or 2 seconds only.
I did not even realize it was a power cut in the engine. But then it happened again in my way back engine still cold and I Was accelerating on the freeway ramp. Suddenly the engine lost power and I went from 65mph to 40mph I tried different things like pushing and releasing the throttle but the more I pushed the more the power was losing. The feeling was like when engine is running with to much gas and few air and it's not able to rev up and tend to stop, same behavior. I do not know what it could be. IT lasted for about 10 seconds and I had shivers on my spine... really feeling so bad!
After 10 seconds the engine recovered back to normality.
I do not know what it could be:
Any hints is very welcome.

I do not know what it could be:
- injection system problem (injectors) ?
- fuel pump problem ? (it would happen more frequently eventually)
- dirty fuel ?
- air flow meter ? (does it exist on these engines)
Any hints is very welcome.

Mine used to do that once in a while, and as younsay, it was intermittent so hars.to.find, mine turned out to be the air flow meter was sticking, got a used one.drom David Biger amd havent had a problem since. (Might have been able.to clean up mine, but i got a bit overzealous and took it apart without marking the cog and at that point i just gave up.)
Hopefully yours is sometbing simple like that too.
Good luck!

What items have been replaced on the car last 3 years?

it's not electrical all gauges works, when it happens engine is like if gas don't arrive to injectors, and rpm start dropping down. it feels like when you run out of gas in the tank... So I was thinking to bad or dirt gas. I did gas in a place where I usually don't.
Anyway is this the air mass flow meter that I need ?

difficult to replace ?
probably the mechanic will tell me $400 for just the replacement part.
I had this problem only the last day i used the car (yesterday). no problem at all before and I Already did 1000mi in less than 2 months.

That's the one, and it's easy to replace.
No "mass" by the way. It's simply an "Air Flow Meter" or "AFM"

Bear in mind that the fuel injection system is electronic....so a fuel problem could be electrical.
So I was thinking to bad or dirt gas.
Remove the fuel filter and empty the contents into a clean jar. What you see will dictate your next steps
