This does indeed sound like a temp sensor problem - most likely a loose connection. Check the connections from the thermocouple to the board on the printhead (thin wires screwed into the terminal block), and also check that the cables are all properly seated into the connectors on the printhead, and onto the electronics board under the printer.
If you are getting wildly swinging temperature readings, it sounds like a problem with the thermocouple or the associated circuitry. The firmware will throw errors if it gets readings that are out of range, and shut down the heaters - which makes sense to prevent damage from the heater running constantly without proper feedback controls.
It's unlikely to be related to the PLA, and even the firmware isn't likely to be the primary cause - although newer firmware may be doing a better job of detecting the problem. (Unless you built your own firmware and have the temperature settings wrong somehow?) Which firmware did you use to update your printer?
hi - looks like it was a loose connection - wiggled the wires around a bit and checked the connections and it works fine now. Will do some more tests today on longer prints and see if it comes back.
thanks for your help!

S-Line Firmware 8.3.0 was released Nov. 20th on the "Latest" firmware branch.
(Sorry, was out of office when this released)
This update is for...
All UltiMaker S series
New features
Temperature status. During print preparation, the temperatures of the print cores and build plate will be shown on the display. This gives a better indication of the progress and remaining wait time. Save log files in paused state. It is now possible to save the printer's log files to USB if the currently active print job is paused. Previously, the Dump logs to USB option was only enabled if the printer was in idle state. Confirm print removal via Digital Factory. If the printer is connected to the Digital Factory, it is now possible to confirm the removal of a previous print job via the Digital Factory interface. This is useful in situations where the build plate is clear, but the operator forgot to select Confirm removal on the printer’s display. Visit this page for more information about this feature.
A year after the merger of Ultimaker and MakerBotQQ, we have unlocked the ability for users of our Method series printers to slice files using UltiMaker Cura. As of this release, users can find profiles for our Method and Method XL printers, as well as material profiles for ABS-R, ABS-CF, and RapidRinse. Meaning it’s now possible to use either Cura or the existing cloud-slicing software CloudPrint when printing with these printers or materials

Welcome! Glad you are loving the printer!
