Engine warning light on Mazda 3

Seven months ago I bought a 2010 Mazda 3 diesel. It has 71,000 miles on the clock and is out of warranty. Yesterday, whilst driving down the motorway, I felt the speed dropping gradually so I pressed on the accelerator and there was no response, then both the engine oil warning light and batter/alternator light illuminated together. The car stopped and restarted fine and I continued to my destination.

Do you know what this problem could be? I do roughly 12,000 miles per annum and am concerned regarding the DPF due to the publicity it has been getting recently. I also started looking up car warranties and found Warranty Direct offer packages for about the £300-350 ballpark, which package would you recommend?

It reads as if the engine was attempting an active regeneration of the DPF, but the DPF was too blocked. I'd get it into a garage and have the fault codes read. This is a Ford/PSA diesel engine used in Focus, Volvos, Citroens and Peugeots, so is well known. You cannot take out a warranty against a pre-existent fault. That is fraud.
