no the ignition module fails aswell as the coil, i guess the bolts could come loose there should be 2 bolts holding the coil to the ignition module

Sounds like the ICM Ignition control module is failing, Its common for these to become intermittent when they start to get warm.
Thats the unit thats affixed to the bottom of the coil.

also the crank position sensor(CPS) might be on the fritz
i seen yer symtoms and it turned out to be the CPS

can the ICM be tested? and if so how?
