2018 Maxima won't stay running. running rich
 

while I was passing a car, I lost power, got limp, but still went to my destination 60 miles away. Once I shut the car off, it wouldn't stay running anymore. I accidentally cleared the codes on OBD scanner, and now it won't stay running long enough to get a code. before clearing I did see a P0101 code....MAF. but the check engine light never came on, instead the traction control and obstruction light came on. They shut off tho after I shut the car off.
