I've had something similar a couple times at age 51 and 52 - maybe not what the OP is experiencing. Mine were followed by a huge adrenaline dump, which made it difficult to complete the ride due to extreme fatigue. I went through lots of testing, nothing showed up. I have not had it since, and I'm 58 now.
