Did the starter come with a new solenoid?
A dirty or ill-fitting battery clamp will do this. use some 80 grit
and sand the INSIDE area of the positive cable battery clamp until it
is clean, shiny, silver-colored lead (or brass) and not the dull grey.
Check the positive cable when it happens and see if it feels warm- or
warmer anywhere along its length than in other areas. Cables can look
fine on the outside and be damaged or corroded inside. Pull the
related fuses and make sure that they are clean (a stretch). If the
car has a fusible link check that. I had one go on a Chevy and it
drove me nuts till I figured it out!
When it happens at night, try letting someone else start it while you
watch under the hood. Watch the battery, but always wear safety
goggles when working around the battery. Have them hold the key in teh
start position while you wiggle the related wiring (battery cables and
starter wires.
