I went thru this problem and many here have also, mine was fuel injectors not holding system pressure and leaking onto the pistons causing warm start stumbling then recovering 10-20 seconds and run great,other parts can go bad to,I replaced a lot that were still good,do a fuel pressure test at fuel distributor for a start before you spend $400-500 in parts like me,search warm start here,lots of threads.luck!
