Other than a bad connection / chaffed wire etc - which can happen - so be sure all is ok there - then the problem is going to be a faulty TPS ... throttle position sensor / switch..
This isn't unusual to happen / go wrong on these - No amount of re learn procedures will cure a faulty one Im afraid - so its a new one that is needed to cure these issues that you have with this one.
The TPS ( sensor ) is at the pedal on this one.... and its this that Im referring too. This can be checked using diagnostic equipment - using live data - it can be checked to see f its working and when its not etc.
Not all garages would be able to do this depending on what equipment they have and their level of knowledge - but I would suggest it would be a good idea to have it checked out as above to confirm the fault ..
You have the TCU - Throttle control unit - but thats inside and a part of the TPM - Throttle position motor ...on the engine.
Your fault codes though would indicate the TPS - at the pedal.
There is also a common fault on these that causes throttle / power loss... Im not so sure this fits the symptoms you describe but it might be worth a consideration... For this - a reprogram / software update has to be performed by either a Fiat dealer - or some garage that has the equipment to do that ....It might be worth you having a word with the local Fiat dealers to have that side of things done in any case - again - as its a common fault.
Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.
Thank you for using FixYa, have a nice day.
