Default 98 ram 7 ignition coils please help

Ok so I have gone through 7 coils i n 3 months some last 2 days others 2 weeks and rare are the months. So when the coil does go truck will die I gotta pull over wait 5 minutes then drive again for a little till I gotta do it again can manage to get home. Put new coil in and all is fine till it happens again. I changed just about every sensor with no avail and a whole lot less cash in my pocket any thoughts

Clean all the ground wire terminals on the motor, coil contact point to the motor. What brand of coils are these?

Find factory coil. These ignition system do not like something else plugged in it, other than factory stuff. Once you change it to factory, problem should go away.

Are you getting any engine error codes? You said almost every sensor. When it dies double check to see if you have voltage at the plug in for the coil. Two connectors, one will have constant voltage, the other will pulse as the engine cranks. Can test this with a test light. If you have a multimeter you can actually look at the voltages. Just search this forum for "test the coil" or something like that. If the pulse side is not pulsing, the the trouble is not the coil. The PCM is not sending the signal for the coil to actuate. If you have a P0320 code, suspect Crankshaft Position Sensor.
