30-1400 engine dying when up-shifting at WOT

I have an '88 Mustang with a 351w. Over the winter I faceplated my TKO 600 and was excited to get to the track. Unfortunately when I up-shift at WOT, the EMS seems to think the engine is shutting off. I logged the "Run Time" when it happened and it reset from ~700 seconds to ~1 second. The timing errors also reset and it seems like it's going through the startup routine after it happens. The log continues through the event so the EMS isn't powering down. I logged the "Battery Voltage" parameter and the voltage does drop before I shift to just above 11 volts. Anyone know what makes the EMS think the engine has turned off?
