Sometimes the starter works, and sometimes not. It sounds like it's spinning, but not connecting.

Driving up hill , Car cuts off and will not restart. Total loss of power . I thought maybe a timing belt , but no clunking sounds as if valves had collapsed or rods bent etc.Turns over good , but not starting .I also think it may be the fuel pump or map sensor..someone help me out here , PLEASE !!

my tranny was rebuilt and was told my lock out was bad

trying to find how to add trans fluid
