Like question asks. Usually left plug stops firing and have to replace coil right or left. Car starts to cut out then when power put to it usually in higher gear then it cuts out all the time running with 3 hot plugs. Thanks

So you your loosing spark to the cylinder closest to the drive belt?Are you loosing spark at the coil?Only on that one cylinder?You swaped coils from left to right to see if the spark loss followed the coil?

Have changed coils both of them.3 times total. The one on theclosest to the drive belt has given out twice.I think once was the one on right. The spark stops at the plug no spark dancing from wire to plug.3rd time in a month getting worse just changed last week. Last time

The spark needs to checked at the coil also to rule out a spark plug wire issue or spark plug issue. If you keep loosing spark on just one cylinder at the coil and you have replaced the coil then you would have a bad ignition module.
