is this a sign?

[bcm]

My 2.3 88 190E,is acting wierd. Early mornings or first start of the day my car starts fine;I've even cut it off a couple of times to make sure and everytime it starts. Now, the problem is when after driving for while and car gets hot; I cut it off it takes about 5-6 turnovers to start. I this a sign for new plugwires or something else?
