I have a 87 F-150 4.9 6 cyl 2wd manual 4 speed
When it warms up and I stop somewhere it is very hard slow cranking
Cold it cranks like a champ
Had the starter rebuilt
I have cleaned all conections
Alt checked good
Batt checked good
When I am having this prob the starter is drawing 386 amps, way high.

Any ideas out there?
Thanks
Tired of having to park on hills

 

No Ideas?

It is running normal temp (about at the "N" on normal)
charging at almost 14 v
