I hope all that time and money was worth it - there are classic symptoms of a blocked gas cap vent. Vacuum forms in tank - no fuel flow - engine stalls. Wait a bit - air leaks in, engine starts again (for a while.....).

To completely elimnate a chassis wiring issue, simply disconnect the mag cable from the engine. The only possible culprit if there are still electrical problems is the coil itself - which you already replaced.

Does the mower die right away (cuts out) or does it sputter to a halt. Sputtering out would indicate a fuel problem. If it just cuts out when hot, then more likely an ignition problem. Your coil may need replacing. Take a close look at the coil wire (spark plug wire) and its routing. Make sure it's not touching part of the engine where it's heating up and has caused a "leak" to ground it out when it gets hot. If all is well then check your spark when the engine is hot and cuts out. Make sure you have a very good blue spark and not a weak one (check it cold first and then compare!). Again, indicating a possible ignition coil problem. Hope this helps and best of luck to you.

Normal maintenance been applied to this rider ? Filters, lube, cleanings ? This sounds like an electrical issue (component hot), or a vacuum in the fuel tank. Next time it 'stops' open the fuel tank up and listen to any air 'whooshing' in.

1 of 2 things happening
first change the fuel filter seams that the gas is vapourizing
