Loss of power while driving

Hello all

I am stuck with a very strange issue. I get a sudden loss of power at random times. It can be in any gear and at any revs. It feels like someone has engaged the clutch and nothing is driving the wheels. If I put my foot on i
the clutch the engine revs up. If I then change down gear and engage the engine again it is like it is engine braking me. I can feather the throttle and it seems like the engine is engaging but no drive. It will suddenly kick back in and pull again. It happened to me on the motorway today and was slightly on the scary side when your speed just plummets and you have no way of powering it out. As I say the engine revs seem fine when clutch is pushed. Needed to engage clutch to stop the engine braking.
This has happened a few times now and I am at a loss as to what it is.

Anyone else had this sort of issue? Or know any starting point to look at.

Thanks in advance for your help

I am not too sure but I would think if the clutch was slipping I would not suffer the engine braking effect. It is like you suddenly tale your foot off the gas even when it is planted to the floor. I try changing gear to kick it back on and it either works or it gives a harder engine braking effect.
Very hard to think what it could be. The car is not used much so has the battery disconnected alot so not to drain the battery. I would leave it connected but the alarm goes off all the time through what I can only assme is voltage fluctuation of the battery. I only mention this as I can't rule out a battery issue although I know it should be running off the alternator at this point.

thoughts.

Since the battery is mostly disconnected, are you driving it long enough for the ECU to store its settings? The ECU programmed settings will be reset to their defaults until a "drive cycle" is completed. Not sure if that would affect the engine at cruising speeds. I know that it can make idling problematic.

Barring that, maybe a fuel delivery problem. Fuel pump or clogged fuel filter?

First thought is the ECU problem mentioned above. Second thought is that you drive the car enough to reset the ECU and then, if you don't plan on driving much, buy a battery tender so that you don't have to disconnect the battery so you won't lose the ECU settings. Doing that "may" solve your problem.
