Hey guys was hoping you could help with a 2012 Transit we got a few months back. Problem started a few weeks after owning it. Transit Will turn off while in route (motor still running) we would loose radio a/c and gauge cluster. It would only turn off for a brief moment. This would happen ~10 times on a 20 min trip. Extremely annoying, because you would have to turn the a/c back on and what not.
I diagnosed the car with a scanner no codes pending or in history. Checked battery it came out good. Checked alternator and it was showing charging volts.
Went ahead and replaced battery any ways and when we did this car would work fine for 2-3 days and then the problem would occur again. Not sure where else to go from here ive done some research and found the single alternator wire has been known to be bad on these cars US and UK. Have not tore it out of the loom yet to see if that problem exists. However the car only has 60k miles would like to get this fixed it is a delivery van for a business and we need it A+.
Thanks guys!

It's probably an ignition relay going bad but since this is the US transit forum there won't be a ton of help for your 2012.

If the engine keeps running it may be in the accessory relay which powers the electrical stuff asid the from engine controls. Just pull them and replace them or tap on them one by one when the issue occurs and see if one will respond and re-connect the power while tapping.
