Just to document:
No issues on way home from soccer game last evening (with the car, anyway; 12 y.o. daughter’s team lost so she had issues...).
This morning started car, drove to store to get the newspaper, drove home. One hour later, went to garage to back car out to wash it. Started it and it caught, them immediately died. Restarted it and it immediately died. Tried again and it started and kept running. Restarted and ran just fine to move into garage after washing.
Weird!
