Hi, I have a 2002 Mazda Protege5 with a 2.0L FS-DE turbo engine. The sprint 500 is running as a piggyback with the stock ecu (stock controls the gauge cluster and other non-tuning related items, sprint 500 controls everything tuning related, timing, fuel, etc....)
A painless wiring relayed fuse block 3 circuit (part # 70113) is supplying power to the ecu.
Crank and cam sensors are cherry hall effect GS100502 sensors.
Toyota 1ZZ-FE COPs in direct fire mode.
GM air and coolant sensors.
Deatschwerks 600CC Injectors
The issue I'm having is that when the engine coolant reaches 140 degree Fahrenheit, the ECU loses power for a split second causing the engine to stall out. Temps below 140, the engine runs beautifully. If I try and restart the engine, it will run for about 30 second and then stall again. Any ideas on what this could be?
I will try data-logging to see if anything funny is happening right before it cuts off.
Questions about the Platinum Sprint series ECU settings or features? Ask here.

You have a wiring issue of some sort. Be sure your CTS is not shorting somewhere. It is the only thing related to engine temp, and nothing in the software will cause it to lose power.
