Default slow crank when warm…

hi
i have issue..i did lot a of
modification on the s2k..
i rebuilded a engine but we notices the cylinder are oval…
relocated battery in the trunk with 0 awg soldering wire.
we installed the FMU not correctly,which will be corrected tomorrow…
however, last year , with all those installed like that,when the car was hot, i had issue with slow cranking when hot,and some staling issue(probably the connection related with fmu )
what guys you think would make my car slow crank when hot?
thanks
thanks

How were the cylinders fixed? To eliminate the "oval."
